Two Saskatoon police officers have resigned in the wake of a sex scandal in the department.

Four other officers have been disciplined in the case that first became public last month. The incidents involved five male officers and one female officer and took place over the past few months, the police service said.

The police service said then that "inappropriate behaviour" had occurred, but it hasn't provided any details of what happened.

Sources have told CBC that the case concerned police officers having sex during office hours in the main police building.

There are no allegations of criminal behaviour or sexual harassment.

Saskatoon police chief Clive Weighill is sending a message to officers and the public, said Alyson Edwards, spokeswoman for the police service.

"The behaviour here was not becoming of our members, and it's not something that we tolerate. Anything further than that, I can't say," he said.

Of the remaining officers involved, one was demoted and the other three were suspended without pay. The longest suspension was one month.

The police officers haven't been identified.
