Residents were woken up after hearing a loud bang described as like ‘a bomb going off’.
The noise was loud enough for neighbours to leave their homes and see if they could find anything to reveal what the noise was.
Local officers are now appealing for anyone with any information to come forward.
Police Constable Luke Bayliss is leading the investigation. He said: “We had several calls on Monday 26 April 2021 at around 9.30pm.
“Following house to house enquiries in the Pinfold Gardens, High Ridge and Sienna Gardens area of Forest Town an amount of shrapnel was recovered.
“We are now investigating this unknown explosion.
“Thankfully we’ve had no reports of any injuries or any property being damaged. No one has seen anything, so we’re asking anyone who saw anything or anyone suspicious in the area at that time to come forward as we don’t know what caused the noise.
“If you can help with our enquiries please call 101, quoting incident 168 of 28 April 2021.”
