A 40-year-old man died following his arrest by the Niagara Regional Police Service, prompting an investigation by Ontario's police watchdog. The incident occurred in the Niagara region, though the exact location was not specified. The man was in custody when the death took place, according to local authorities.

The police watchdog, known as the Ontario Office of the Independent Police Conduct Review Director, has begun an inquiry into the circumstances surrounding the death. The watchdog is responsible for reviewing complaints against police and investigating deaths in custody.

This is the second such investigation in the Niagara region this year. Last month, a 35-year-old man died after being detained by police in the same area. Both incidents have raised questions about police procedures and the use of force. The watchdog is expected to release its findings within weeks.

The death has sparked public concern and calls for greater transparency in police operations. Local community leaders have expressed support for the investigation, emphasizing the need for accountability. The case remains under review by both the police service and the watchdog.
