remain in the middle of the room (They are the " Policemen "). 
The Patrol write a description of the " Criminal " who,
may be anyone in the room except a " Policeman ". 
The Patrol Leader gives the written description to the
two " Policemen " of his own Patrol, who arrest the
Criminal " and take him back to their Patrol. 
Cot-Cases. 
 Patrols are not allowed to discuss who is to
be the " Criminal, " and each Scout in turn has to write one clue, and may read all the clues that have been written
before. 
 There is only one " Policeman " per Patrol, and
he takes round the paper to collect the description.
