Police are looking for three people seen on surveillance video in the moments before an attack on two teenage girls.

The attack happened in Downtown Stamford, around the corner from Greyrock Place. Officials say the Darien teens were leaving a movie theater when two female suspects approached them, followed by a man on a bike.

One of the victims suffered severe cuts to her face. Police believe the attack was completely random.

People who live and work in Downtown Stamford say they are shocked by the attack, as well as other recent random acts of violence. Last month, a man fired several rounds into a crowd outside a nightclub, hitting five people.

Anyone with information on the incident is asked to call police.
