Detective Constable Natalie McNally said: “I would appeal to anyone who may have noticed any suspicious activity in the area or who has any information to contact detectives at Musgrave on the non-emergency number 101.
“Or, if someone would prefer to provide information without giving their details they can contact the independent charity Crimestoppers and speak to them anonymously on 0800 555 111.”
