A Bronx father who served more than two years at Rikers Island for a knife attack he didn’t commit was stabbed to death early Saturday outside of a rowdy bar, police and family members said.

Baraquiel Castelan, 32, was stabbed in the neck during an altercation on Feb. 3 outside of El Chicanito, a bar and restaurant on East 153rd Street in Melrose, cops said — leaving some locals to question how nightspots are affecting the neighborhood.

“He would give without getting anything in return,” Olivia Castelan, the victim’s 29-year-old sister, said of her brother.

“He would see someone fighting and he would try to break it up — he never was violent with anybody,” she added. “He gained the community’s respect.”

Outside the bar on Monday a makeshift memorial was set up for Baraquiel, where community members left candles spelling out B-A-R-A, the first letters of his name.

Baraquiel leaves behind two daughters, 9 and 1, the eldest “in shock” over the sudden death of her father.

“She just can’t believe it. But she says ‘now he’s with my grandpa. Now they’re both together,'” Olivia says, referring to her and Baraquiel’s father, who was murdered in Mexico last year.

The family has dealt with several recent tragedies, including Baraquiel’s wrongful 27-month incarceration at Rikers Island, which devastated both him and his family, relatives said.

“When he was in Rikers we felt like we were in there with him,” Olivia said. “He had PTSD … Mentally it took a toll on him.

“That was really hard on us,” Olivia added. “You are out of your daughters’ life, you’re paying for something you didn’t do.”

After his exoneration and release, Baraquiel was just starting to put the pieces of his life back together.

“He turned his life around after that. He took care of his daughters, he was a great dad,” she said, noting that the family still has a pending legal case against the NYPD Baraquiel filed in 2018, which they “plan to pursue” even after his death.

On the night of her brother’s killing, Olivia was sickened to see it was business as usual at El Chicanito.

“I want them to shut that place down. Someone was murdered there. Killed there. That same night I went over there and they were open,” she told The Post.

“They get to move on but our lives stop? Our life is on pause? They just to get to move on, party, to continue their business but we have to make plans to bury my brother.”

El Chicanito operates in a nondescript cement building with only two windows, which are both boarded up. Neighborhood residents and business owners said the watering hole sometimes attracts violent patrons.

“The community is very afraid. The residents are terrified. Everybody talks and complains and the city does nothing,” Steve Jacobs, owner of A&Z Electronics located on the same corner as the bar, told The Post.

Eivette, said the bar and another night spot aimed at teenagers, have had the neighborhood on edge.

“There’s always blood here,” Eivette said. “Just a year ago someone got stabbed from there and died right there.”

Cops are soliciting leads from the public and have released photos of a possible suspect in the attack, but no arrests have been made as of Monday.

There was no answer at a phone number listed for El Chicanito Monday afternoon.
