Santa Rosa police this weekend arrested three people and found a 16-year-old carrying a BB gun that looked like a semi-automatic handgun, police said Monday.

Called by neighbors about suspected gang members, including one thought to be armed with a gun, officers responded to an apartment complex on Bellevue Avenue in south Santa Rosa at about 11:30 p.m. Saturday, Sgt. Eric Goldschlag said.

Due to the report of a possible gun, officers held four teens and an adult at gunpoint. They found no real gun but a 16-year-old had a realistic-looking black, plastic BB gun in his waistband, Goldschlag said.

The teen was cited for possessing alcohol.

Officers detained a 14-year-old wanted on an arrest warrant and took him to Sonoma County juvenile hall.

Also arrested was 24-year-old Jose Godoy of Santa Rosa, on suspicion of battery on a police officer and obstructing justice. Officers reported Godoy, who was in violation of his probation, fought as he was taken into custody.

Godoy has been active in youth protests over the fatal shooting of 13-year-old Andy Lopez last year by a Sonoma County sheriff's deputy. The deputy reportedly mistook the airsoft BB gun Lopez was carrying for a real assault rifle. The shooting remains under review by Sonoma County District Attorney Jill Ravitch.

Godoy was released from Sonoma County Jail after posting bail on the misdemeanor charges. It was his second arrest since late April, when officers detained him on suspicion of contributing to the delinquency of minors after he was found in his car with several teens and marijuana during school hours, police said.

Godoy has said he believed police were targeting him. Police officials have denied they are seeking him out.
