Thanks guys for the help.

I did exactly as you all adviced. I tried calling from a different number and he hung up saying 'Only Arabic' and there was a lot of background disturbance. I tried calling again and he did not receive.

I went to the police station and even though I struggled to get the message across, they have taken down his car plate and mobile number and asked me to come back in a week to find out the progress..

Thanks again to all who helped. I appreciate it.
