A gunman opened fire near Brooklyn College Tuesday afternoon, leaving one man in critical condition and sending panicked pedestrians running for their lives.

In surveillance footage released by police Wednesday, the victim, 18-year-old Tyquan Sewell, can be seen walking along a crowded sidewalk in front of a McDonalds at 2154 Nostrand Ave in a white tank top. According to police, the victim had just had an argument with a man who was already inside of the restaurant.

As Sewell tries to open the door, the suspect, dressed in a red jacket and light colored pants, can be seen bursting out of the McDonalds firing multiple shots with a .32 caliber Smith and Wesson revolver.

One bullet grazes the young man's head and he can be seen falling to the ground as both of his shoes fly off. The gunman continues firing as he advances on Sewell, who is left rolling into the street after being hit in the groin, leg and torso. The bustling sidewalk clears quickly and an NYPD van can be seen pulling up seconds after the shooting.

After the shooting, the suspect, along with two accomplices who passed him the gun, ran back into the McDonalds and may have exited through doors on the other side of the restaurant onto Flatbush Ave.

Sewell was taken to Kings County Hospital in critical but stable condition, according to EMS officials.

Police are now looking for the three suspects, all black males. The shooter was dressed in a red jacket and light colored pants, the second suspect in all black and the third in a white shirt and dark jeans.

Anyone with information in regards to this shooting is asked to call the NYPD's Anonymous Crime Stoppers Hotline at 800-577-TIPS.
