Sunnyside police called in SWAT teams after a robbery suspect fled into an attic in Sunnyside on Wednesday.

Two young men allegedly threatened a 19-year-old man with a knife and demanded money near South First Street and Lincoln Avenue about 2 p.m.

An officer who was nearby saw the suspects and immediately arrested a 16-year-old. The other suspect, later identified as Matthew Ray Garcia, 19, ran into a nearby home and refused to come out.

Police obtained a search warrant and called SWAT because the suspect was known as a gang member, according to police.

Officers found Garcia in the attic. He was arrested on suspicion of robbery and burglary. The other suspect was arrested in connection with the robbery.

The victim was not injured.
