Bonjour pouvez vous m’aider svp

Last night as I went out of the cinema, I saw three men coming out of the bank. First, I didn't realised what was happening. They were carrying machine guns and they were wearing masks on their faces. They were carrying also big black bags. They were running fast in the street when suddenly one of them dropped one of the bags. He looked panicked and suddenly he pick the back and started to run. The other two robbers were already in the car which was moving off. The car suddenly stopped and the last robber jumped in the car. They drove off. I was scared so I didn't watch the scene carefully to report it to the police.
