Stockholm - A Swedish prosecutor Monday dropped a probe over an explosives scare that caused the precautionary shut down of a nuclear reactor in May.
A so-called smear test had triggered an alert for an explosive at a spot security check on May 21. Two men, aged 53 and 44, were arrested on suspicion of planning sabotage at the Oskarshamn nuclear plant but were released the following day.
They have remained under suspicion until Monday.
Subsequent tests indicated that "a container of shaving cream" carried by one of the men contained traces of the explosive TNT or trinitrotoluene, but authorities could not explain how this occurred.
