“We are grateful that no-one was hurt or injured in the incident, but we would like to determine the exact circumstances as to what happened that night.
“I would like to thank everyone who has helped with our investigation so far and would urge anyone who has any further information, even if you believe it to be irrelevant, to contact police on 101 or email email@example.com quoting incident number 1263 of 15 May 2016.”
