Two people were whacked in the head with a baseball bat by the same apparent assailant in separate attacks in Queens Saturday.

The first victim, a 46-year-old man, was hit in the back of the head with a bat at Astoria Park around 6:10 p.m., according to the police.

The suspect, described as male on on a skateboard, fled the scene cops said.

The man was taken to Elmhurst Hospital in stable condition.

A short time later, a 79-year-old man was struck in the forehead with a bat 19th Street and 20th Avenue — just a few blocks from the park, cops said.

The assailant was described as male matching the description of the suspect from the earlier attack.

The 79-year-old was taken to Cornell Hospital and is also in stable condition, according to police.

Police canvassed the area and a person of interest was taken into custody. No charges have been filed.

It’s not clear if the perpetrator was known to the victims.
