Some police were looking for my friend because they wanted to speak to him about a crime.
Do you know what was going on?
I think they want to question him to see if he was involved in a crime.
I know you want to protect your friend, but if the police are looking for him you need to tell them where he is. If he's committed a crime, he will have to pay for his actions. You should tell the police where he is because what he's done is wrong.
The police are bad people. He didn't do it.
Wanting to protect your friend from the police is understandable, it sounds like you have had some bad experiences with them. But, the longer your friend hides from the police, the more guilty he looks. Offer to go to the police station with him for support.
