MADRID (AP) -- Spanish regional government authorities say a man has beheaded a woman in a supermarket on the Spanish resort island of Tenerife in the Canary Islands.

The suspect, believed to be a homeless Bulgarian man with a police record, was detained by security guards after he ran out of the supermarket with the head in his hands.

A witness told broadcaster Cadena Ser that he saw the man drop a bloodstained woman's head on the pavement after coming out of the store.

A regional government spokeswoman said the suspect is believed to have entered the shop, stolen a knife which he then used to assault and behead the woman whose identity hasn't been released.

The official spoke on condition of anonymity in keeping with department regulations.
