Three Jewish men were punched in the face Monday morning in what police believe could be a pattern of attempted robberies in a Brooklyn neighborhood.

The first attack happened at 80 Ross St. in Williamsburg around 5 a.m. when three men came up behind a 71-year-old man, pushed him to the ground and went through his pockets, according to the NYPD.

One of the men then hit the victim in the face and the group took off, cops said.

Two other similar attacks were reported just a few blocks away around 5:30 a.m. — one at 626 Wythe St. and another at 91 Clymer St., according to police.

The Jewish men, ages 56 and 67, were punched in the face and had their pockets gone through by three men, cops said.

“Give me your money,” one of the attackers said to the 67-year-old before hitting him, according to cops.

Nothing was stolen in any of the attacks, police said.

Two of the victims were taken to Bellevue Hospital Center, cops said.

The NYPD Hate Crimes Unit was looking into the attacks Monday, Chief of Detectives Dermot Shea tweeted Monday.
