Three assailants died Thursday in an attack on the head of Venezuela's Indepabis consumer protection agency, who escaped unscathed, police said.

"We know that an irregular situation arose. Three people died in the event," deputy policy chief Douglas Rico told reporters.

"Two live grenades are found, one of which went off and caused the death of one (person), and we are in that process of determining what it was that really happened there," he said.

The deputy chief did not say how the other two assailants died.

Indepabis director Eduardo Saman was not hurt, Rico said.

"Thank God he was able to make it in time to the (building) of the Bolivarian Intelligence Service, where he ended up sheltering," the deputy police chief said.

Rico declined to offer further details pending completion of the investigation at the scene.

Saman's bodyguards repelled the assailants when they tried to rob the official as he left his office in downtown Caracas, according to unconfirmed media accounts.

Crime is a major problem in Venezuela, where the homicide rate is 54 for every 100,000 residents, compared with a global median rate of 8.8 murders per 100,000. EFE
