A 57-year-old Spanish builder who reportedly liked dressing up as a sheriff shot and killed four people including his former boss yesterday, police and media said.

Armed with either a rifle or shotgun, he shot a father and son who were his employers in the mountain town of Olot, northeastern Spain, before driving his car to a bank where he killed two staff, a man and a woman, they said.

He surrendered shortly after the rampage, one of the worst recorded in Spain in at least two decades.

“At about 9 a.m., Catalan police officers were alerted to the death of two people in an establishment,” the Catalan police said in a statement.

“Half an hour later they received information that a man responding to the same physical description entered a banking establishment and killed two employees,” they said.

Soon after, “the man suspected of being responsible for the four deaths was arrested by local police.”

Police identified him only as “Pedro P.P”, aged 57 and of Spanish nationality.

His motives were being investigated, a police spokesman said, although several reports pointed to a grudge related to finances and a recent dismissal from work.
