Buddy (born in) 1982,
Welcome to this beautiful site, first!
About 'such' incidents, which are common, and the 'excuse' which is also too common, I would advise you not to go by what he says, as it is often suggested to conceal the hard and bitter facts, as it might disturb the relations, even as knowing it later, that you had hidden, causes worse problems, still one usually hopes, it would not happen, as it is often said to be ready for the worst, but hope for the best. Do not discard him, just because he lied to you. Your fears may, yeah may be, correct, but he may also be correct, in the following ways -
1. May be the police has wrong information about him, or someone might have lodged false complaint against him bearing some grudge against him.
2. He might be the victim (not the accused, as you or the police believe) of some conspiracy.
3. May be he had to take shelter there as he might have no way no other option.
