A couple walking home from Davis Square was robbed Saturday when a thug stuck them up with a silver and black handgun.

Both victims described the suspect as a white male about 5 feet 10 inches tall wearing baggy blue jeans, black sneakers, black hooded jacket and a blue baseball cap, police said. His face was clean-looking with a mustache and goatee, police said.

Police said the crook surprised the victims when the girlfriend slipped and fell to the ground, going up the first step to her home. The suspect ordered the boyfriend to drop a bag containing a bottle of wine  on the ground and asked for his wallet, police said. The boyfriend handed over the wallet.

When the crook saw the girlfriend holding a purse, he ordered her to give it up, police said. The thug then grabbed the bag and ran down Morrison Avenue towards Willow Avenue, police said. The suspect remains at-large.
