On behalf of the Policing Board I would like to offer deepest condolences to the family, friends and colleagues of this young women.
They will have received the terrible news this morning and will be devastated by this tragic event.
Our thoughts are also with the two police officers in the car at the time of the collision, who managed to escape without serious injuries.
To lose a colleague, out on patrol protecting the community, is a terrible blow to the PSNI and I would appeal to anyone who has any information about this incident to go to the police immediately.
