Police say the two men arrested in connection with the burglary at Jumpin'Jacks bouncy castle hire in Rowley Regis were released because there was insufficient evidence to charge them.
Sergeant Leighton Shingles from Sandwell Investigation Team said:
“We have conducted a thorough investigation into the theft and although two men were arrested in April, after consultation with the Crown Prosecution Service, it was found that there was insufficient evidence to charge them.
“I would urge anyone with information which will help with the enquiry to contact police on 101.”
Owner of the business, Chris Winters, has set up a Facebook page showing CCTV images taken on the night, to try and identify those responsible.
