On the morning of 7 May 1981, Lieutenant-General Joaquín Valenzuela was travelling in a military vehicle accompanied by Lieutenant-Colonel Guillermo Tevar Saco, NCO and bodyguard Antonio Noguera García and Private Manuel Rodríguez Taboada, who was driving the car. When they halted at a traffic light on Calle Conde Peñalver, a motorcycle with two ETA members on board came up beside the vehicle. The pillion passenger, Henri Parot, placed a bag with an explosive device on the roof of the vehicle, just above the driver’s seat. The motorbike then sped off before the bomb went off. Twenty people were injured in the explosion and three of the soldiers were killed. Lieutenant-General Valenzuela survived the attack but was seriously injured.
