Fairfax police have released a video of a man walking in a gated neighborhood in Herndon where a family of four was abducted from their apartment, robbed, and then left in a remote area last week.

The apparently random attack began about 9:30 p.m. after a father dropped off his wife, teenage son, toddler and a friend at the family’s apartment and then went to park the car, police said.

The attacker followed the family into their home, ordered everyone to the family car and told them to drive to a nearby ATM to withdraw money.

The man implied he had a weapon, but none of the victims saw it, police said.

The man then told the father to get into the car trunk and ordered the family friend to drive to a secluded business park area off Innovation Avenue, police said.

There, the man freed all of the victims except the father, who was still in the trunk, police said. The others ran and flagged down a bicyclist, who called for help.

At some point, the attacker fled on foot, police said. When the father realized that the assailant was gone, he was able to escape.

The man is described as black, in his 30s and lean. He is about 5 feet 9 inches and wore a dark hat; a dark, baggy sweatsuit; and black athletic shoes, police said.

Police have released a sketch of the suspect.

Police ask that the man, or anyone who recognizes him, contact authorities at 703-691-2131 or text “TIP187” and a message to CRIMES (274637).
