Officers brought Daniel Bradley to the jail wearing a Spiderman costume. The 21-year-old is accused of trying to steal a woman's purse over the weekend in Merced.
Investigators say Bradley was wearing a jacket over his costume during the attempted robbery, and the victim thought she saw a gun tucked in his sleeve.
Police say she ran away and screamed for help. They later caught Bradley, and found the jacket and a metal pipe in the bushes.
Investigators say Bradley told them the costume was part of his disguise.
