An 11-year-old girl testified Tuesday that when she was six years old she was sexually assaulted by her babysitter, a former Mountie.

Colin Allooloo has pleaded not guilty to charges of sexual assault and sexual interference. He's being tried before a judge and a jury in Yellowknife.

The incident is alleged to have happened in Inuvik, N.W.T., between September 2010 and June 2011. Allooloo resigned from the RCMP in October 2010.

The girl's testimony was broadcast for the jury on a television while she testified from another room in the courthouse. 

She cried as she testified that while Allooloo was babysitting her one night, he came into her room, took off her pyjamas and touched her sexually.

During his cross examination, defence lawyer Jay Bran questioned the girl's memories because the assault is said to have taken place five years ago. Bran also suggested the girl made up the story because she didn't like Allooloo and wanted to get him in trouble.

The girl's mother and grandmother also testified.

The Crown has now wrapped up its case. Bran said the defence hasn't decided if it will call any witnesses.

The trial continues Wednesday.
