The NSW Police Force has been rocked by the actions of another apparently suicidal officer.

This time a high-ranking officer is in a coma hospital after trying to commit suicide in a hotel room, The Daily Telegraph reports.

Superintendent Paul Nolan, 54, was recently suspended from the force because he is under investigation by the Police Integrity Commission.

He was found unconscious about midnight on Tuesday.

The nature of the PIC investigation is unclear.

This latest incident comes after Commissioner Ken Moroney last week expressed concerns about mental health issues among the force, publicly telling his officers that it was “OK to cry“.

In January, 29-year-old Constable Greg Lundberg committed suicide with his pistol in Menai police station due to personal problems.

Last month a 39-year-old senior constable barricaded himself inside Earlwood police station and threatened to take his life.

Earlier this month, 27-year-old Constable Nathan Hearps from Quakers Hill plunged to his death from a Surry Hills apartment block, News Ltd reports.
