A man was robbed of $6,000 in Sunset Park after being shoved into the trunk of his car and bashed in the head with a gun multiple times, cops said.

Four men walked up to the 25-year-old at the corner of 16th Street and 3rd Avenue at about 2:20 a.m Saturday and attacked the man, according to police.

A video released Sunday shows the attackers shoving the man into the trunk and beating him.

The armed robbers also made off with his cell phone and watch, cops said.

The victim refused to be treated by EMS.
