SPANISH police searched the Madrid headquarters of the ruling conservative Popular Party for explosives today after a man rammed his car into the office entrance.

There were no reports of injuries and National Police spokesman Antonio Nevado said that the attack did not appear to be terrorism-related.

The driver was arrested and bomb disposal experts scoured the area in and around the Genova Street office in central Madrid.

Police found two gas cylinders and an unidentified substance in the car.

But Mr Navado was quick to rule out terrorist action.

“Everything indicates it was a personal action that has nothing to do with any type of terrorist action,” he said.

“It’s a person who is suffering from economic problems.”

The car had smashed through a roll-down metal entrance shutter and two sets of doors.

Police sealed off the street and surrounding roads and two subway stations were closed.
