The Garda Síochána Ombudsman Commission (GSOC) has deployed a team of investigators after an incident in Co Monaghan in which a man died and a Garda was injured.

The man - who has been named as 47-year-old Stephen Marron - died following a two-car crash at Main Street in Castleblaney at 11.30pm on Tuesday.

Shortly before the crash, a Garda had attempted to stop a silver Audi A6 close to Castleblaney Garda Station.

This car drove off and the Garda was dragged by the car for about 500m before it crashed into another car, a Skoda Octavia, on Main Street.

The driver of the Skoda was pronounced dead at the scene.

His body has been taken to Our Lady of Lourdes Hospital Drogheda, where a post mortem examination will be carried.

The injured Garda - 31-year-old Michael Devlin from Monaghan Garda Station - was treated for facial, head and leg injuries at Our Lady of Lourdes Hospital in Drogheda.

He has since been discharged from hospital.

A 34-year-old man was arrested at the scene.

He is being detained at Carrickmacross Garda Station under Section 4 of the Criminal Justice Act.

GSOC said it received a referral under Section 102 the Garda Síochána Act 2005.

This provides for an independent investigation of any matter that appears to indicate that the conduct of a member of the Garda Síochána may have resulted in the death of, or serious harm to, a person.

GSOC has deployed a team of investigators to the scene, and an examination of the incident is continuing.

Any witnesses are asked to contact Carrickmacross Garda Station on 042-9690-190, the Garda Confidential Telephone Line on 1800-666-111, or any Garda station.
