Tonight police were seen guarding the house from the back and front, while Explosive Ordnance Disposal (EOD) experts later arrived to inspect the inside of the house.
The house was then sealed with a notice: “Attention owner/resident. The police have entered your property and sealed it to prevent unauthorized entry. For further information please call 101.”
A neighbor, who did not want to be named, said forensic investigators in white suits had been to the house earlier and taken photos inside the house. Residents reported seeing the camera flash through the front door.
In a separate incident, police were called to Collingwood Road in Billingham at around 11pm on Saturday (September 17) to deal with a domestic matter at a residential address.
