Interiors Minister Victor Catan told reporters on Saturday it is not yet clear whether the man apprehended by the police in the case of the grenade explosion on October 14 is the actual author of the 'attack'. His alibi is now being checked out, Catan said. “It remains to be seen if this is really the man we were looking for. This morning we received additional information about other potential suspects. Then we'll select the most reliable version” The minister went on to add that the investigation is considering several versions of what happened, including a terrorist attack, and is looking for other suspects matching the sketch based on witness accounts. Over 40 people were hurt in a grenade explosion on October 14, at an open-air concert marking Chisinau's dedication day.
