The teens struck again. This time at a festival Friday night in the North End.

Boston police arrested one person, summonsed five to court, and wrote or are in the process of writing at least 20 different reports based on underage drinking incidents at the Fisherman’s Feast, an annual festival in the historic Italian district that commemorates the devotion of fishermen from Sciacca, Italy to Madonna del Soccorso, or Our Lady of Help.

The department has received “an abundance of complaints” from the community of underage drinking at festivals in the North End, officers wrote in one report.

In the past few years, the festivals have become “inundated” with minors from outside the city “who congregate around the festivals and drink in public, start fights, and cause other disturbances,” the police report said.

Friday night was apparently no different, according to law enforcement descriptions in seven different police reports provided to the Herald.

In one of the police reports, officers said they arrested 19-year-old Nicolas Zannino, who they saw drinking a 700 milliliter peach hard seltzer in the crowd at about 10:40 p.m. Zannino told cops he was 21 years old but did not have his ID on him, according to the report.

“As officers were escorting, the suspect began to turn his body and break free from officers in an attempt to get away,” the police report said. “At this point, officers were in the middle of a large crowd surrounded by patrons of the festival. Officers brought the suspect to the ground and placed him in handcuffs.”

Zannino was charged with disorderly conduct, resisting arrest, underage drinking, and drinking in public. Boston police officers said they had “dealt with the suspect at the feast the week prior,” according to the police report.

A pair of festival volunteers, who asked not to be named, said hundreds of teenagers surrounded a stage next to the Madonna Del Soccorso Society Fishermen’s Club on North Street. Many in the crowd, the volunteers told the Herald Saturday, were underage drinking as a band was playing after 10 p.m.

One volunteer said the crowd was not aggressive but there were so many kids that you could barely walk down the street.

“They [cops] were undercover. They had to call in more,” the volunteer said. “And then they shut it down.”

Another volunteer said the festival was shut down around 10:30 p.m. and a band that was supposed to close out the night was canceled.

But Fisherman’s Feast Co-Chairman Danny Puccio said all of this is false information.

“I’m the feast chairman. You can quote me. That’s false information. There were a lot of kids at the feast having a good time,” he said during a brief phone call on Saturday. “The feast went on as usual. Nothing changed. There were no arrests made. And we’re actually looking forward to tonight.”

Speaking to the Herald a short while later in person at the feast, Puccio said a band did not get canceled and the feast shut down only 15 minutes early “just to support the cops.”

“Listen, I’m not sugarcoating it. The kids were here in groves. But they weren’t rowdy,” he said. “They weren’t causing trouble. The band was keeping them entertained. They were dancing. Other than seeing kids make out in the crowd, we didn’t have any issues.”

Multiple sources familiar with the incidents Friday night said reinforcements from the department’s first-half shift in the downtown area had to be called in to support the police officers working the festival.

Boston police spokesman Sgt. Det. John Boyle declined to comment on the police presence at the festival and whether an additional shift was called in.

Boston Police Patrolmen’s Association President Larry Calderone said there is a problem with teens disrespecting police and Boston neighborhoods, something people “saw again last night in the North End.”

“In response, we need elected officials willing to send a strong, clear message that the people of the North End aren’t going to tolerate delinquent behavior from teenagers who think its okay to disrupt one of the city’s most cherished festivals or disrespect the officers there to safeguard the families attending.”

Ralph Ravesi, who was manning the Sea Level Raw Bar at the festival on Saturday, said there were hundreds of teenagers surrounding the stage Friday night. He described the crowd as “very aggressive” and as “elbow-to-elbow.”

Ravesi said he picked up about 50 nip bottles on the road as teenagers were underage drinking.

Mary McGee, an executive board member of the North End/Waterfront Residents Association, said there have been “packs of suburban teenagers roaming around the neighborhood” since Thursday.

“You recognize them because they all have backpacks and water bottles filled with booze. And Thursday night, one of them actually defecated in the toddler playground on Prince Street. And unfortunately, my two-year-old granddaughter found it,” McGee told the Herald by phone Saturday. “That’s where the neighborhood toddlers have their birthday parties. There was one scheduled for this afternoon, I don’t know what the heck they were going to do about that.”

The teenagers have been a problem at festivals for multiple years, McGee said.

“It’s a problem. They’re not local. Kids are coming in from out of town,” she said. “They’re very destructive.”

Multiple police reports reviewed by the Herald detail both undercover and uniformed Boston police officers stopping underage drinkers at the festival Friday.

In one report, police said they approached a pair of kids who “attempted to conceal their alcohol and began to tense up.”

“Officers were forced to physically retrieve the alcohol and separate the two minors with alcohol from their friend group, who grew more animated towards officers,” the police report said. “During the brief struggle to separate the parties from their friends, officers were able to recover alcohol from [redacted].”

Both the male and female suspects “put up significant resistance to notify parents,” the police report said.

“[Redacted] even went so far as to say he doesn’t have a mom and ‘he lives with his aunt,’” a police report said.

The kid eventually admitted he did have a mom and provided police her phone number, according to the police report.
