Cape Breton children's entertainer Dale Rancourt, better known as Klutzy the Clown, has been charged with sexual assault, sexual exploitation and sexual interference, say Cape Breton Regional Police.

Rancourt, 51, of Gabarus, appeared in Sydney provincial court this afternoon.

The alleged victim is a girl under the age of 16.

'Serious, indictable offences'

"These are serious, indictable offences and given the circumstances, the nature of the charges, the Crown has to assess its position," said Crown prosecutor Sheldon Nathanson.

"Given the concern for the public at this stage we're going to oppose his release and we're going to review it tomorrow."

A bail hearing is scheduled for Tuesday. At that time Rancourt may call evidence to show why he should be released.

Police have not released any details of their investigation or provided any information about the alleged victims.
