A Multi-Agency Triage Team (MATT) prototype has been operational from July 2018 and is due to run until March 2020.
Supported by the Transformation Fund, this project involves two police officers, a mental health nurse and a paramedic working together to respond to people with mental health problems, aged 18 and over, who have accessed the 999 system.
The service currently operates on Friday and Saturday nights, between 7pm-7am, primarily covering areas within the South Eastern Health
and Social Care Trust.
To date there have been over 150 referrals to this service.
Recently a BBC camera crew spent time with the team to see first-hand the work they are doing to support some of the most vulnerable in society.
