The area around the Ruppelstraat was cordoned off while the bomb disposal team did its work. Local residents that had been evacuated from their homes have since been allowed to return.
Last week there were a number of incidents in Antwerp in which cars were burned out of blown up by grenades.
Ten days ago a car burned out in the same street and last Thursday night a number of grenades were thrown under parked cars in the area. Police are investigating whether the incidents are drugs related.
