policeblotter_sfa.jpgA man accused of attacking his brother with a power drill at a home in San Francisco’s Sunnyside neighborhood on Sunday morning was let out of jail days earlier where he was being held on suspicion of a hate crime attack, police and prosecutors said today.

The power drill attack was reported at 9:40 a.m. Sunday at a home in the 100 block of Judson Avenue.

Kevin Guerin, 57, was in jail on assault and criminal threats charges with hate crime enhancements until last Tuesday when a judge lowered his bail over the objection of prosecutors, allowing him to be released, district attorney’s spokesman Omid Talai said.

Guerin then went to stay with his 61-year-old brother at the Judson Avenue home where the attack occurred four days later, police spokesman Sgt. Mike Andraychak said.

The brother had gotten out the drill to fix a broken door latch when, for an unknown reason, Guerin forced him into a bedroom, pushed him onto the bed and got control of the drill, Andraychak said.

Guerin allegedly threatened his brother’s life then squeezed the trigger of the drill and brought it to his head and face, according to Andraychak.

After a struggle that caused the drill bit to fall out, Guerin allegedly struck his brother in the head with the drill and told him to leave the house, Andraychak said.

Officers responded and arrested Guerin while his brother was taken to a hospital to be treated for his injuries, which are not considered life-threatening.

Guerin has been charged with assault with a deadly weapon, battery and making criminal threats, with enhancements for having committed the offenses while out on bail in another felony case, Talai said.

He is scheduled to be arraigned on the charges at 1:30 p.m. Tuesday at the San Francisco Hall of Justice.
