Police in New Brunswick are investigating the circumstances surrounding the death of a 43-year-old man while in custody.

The Tracadie-Sheila man was arrested around 4 a.m. Sunday after police received complaints that an intoxicated man had been knocking on people’s doors in the area.

He was placed into custody and released shortly before noon.

Three hours later, police say they received more reports that the same man was trying to break into a home and they arrested him a second time.

Police say it is policy to conduct routine checks on those in custody every ten to 15 minutes, and during a regular check at 9:25 p.m., the guard found the man unresponsive.

An ambulance was called while police tried to resuscitate him, but the man was pronounced dead upon arrival at the hospital in Tracadie-Sheila.

An autopsy has been ordered and the Bathurst Police Force is leading the investigation into the circumstances surrounding the man’s death.

The man’s name has not been released, pending notification of his family.
