The National Gallery was broken into (by someone) late last night. The alarm system had been broken by the thieves before a window was climbed through (by them). Some priceless works of art were stolen (by them). A gateaway car was used to escape (by them). Some suspects have been questions by the police. The thieves have not been caught yet (by the police).
