The police have the power to detain a person. However, this must be in the interest of all parties and for a proper purpose.

The public places much faith and hope in the police. The police, too, from time to time, remind the public that they are the friends of the public. So if there is any kind of trouble or likely to be trouble, the immediate thought is to call the police.

In times gone by, the well-known number for help was, and I believe still is, 999. It is a number that is so easy to remember.
