A 26-year-old man armed with a knife was arrested following an incident at a property in the Hightown area of Wrexham yesterday evening.
Police were alerted to an incident at a property on Bennions Road at 6.22pm where a man armed with a knife had made threats to people inside the property who were known to him.
The Armed Response Unit attended along with other police units and attempts were made to make contact with the man.
After a short period of time the knife carrying man made his way out of the property where officers arrested him on suspicion of a public order offence and arson.
Officers had noticed a fire at the property upon attending the scene which was quickly brought under control by members of the North Wales Fire and Rescue Service, who had been placed on standby by police.
Four homes were evacuated as a precaution whilst firefighters tackled the fire.
The man was taken to Wrexham Maelor Hospital as a precaution following the incident and has since been released and was last night in police custody awaiting questioning.
Chief Inspector Mark Owen from North Wales Police said: “We are extremely grateful for the excellent support provided by colleagues from the Fire Service who responded rapidly to the fire thus preventing damage to other properties.”
