It probably comes as little consolation to these Cambridge residents that a thief targeted the wrong home in a brazen daylight robbery.

But that's what happened when an armed man barged into an Arthur Fach Drive residence last Friday afternoon.

Police spokesman Olaf Heinzl says the occupants were robbed of a small amount of money and electronics but weren't injured.

Heinzl says the suspect is black, 30, 6-feet, thin build with a small amount of facial hair.

He was wearing a white tee-shirt, black shorts, a baseball cap and sunglasses and carrying a bag.

Heinzl says police believe the suspect meant to target a different residence.
