They didn't overpower him, once he ran away and once the victim escaped him when he relaxed and loosened his grip.

Yes, he fled the scene during the first incident and left the girl sitting on the ground. The second one was able to get away from him and ran off.

And why wouldn't he pursue the second one to complete the job he'd started?
