A teenager is wanted in connection with a robbery in Aylesbury.

Eighteen-year-old Adelin Olteanu should not be approached if you see him - but urgently call 999.

Olteanu is known to visit Aylesbury, Manchester, Bradford, Leeds, Sheffield and London.

Police want to speak to him after an 87-year-old man was hit in Aylesbury town centre at around 10pm on March 17 and his wallet - with bank cards, £10 cash and personal items - was stolen.

The pensioner suffered a serious head injury and had to be rushed to Stoke Mandeville Hospital.

Designated investigator Hannah Mitchell of the Aylesbury Priority Crime Team, said: “Despite efforts to locate Olteanu, we have as yet been unable to do so.

“I am appealing to anybody who knows where he is to get in touch with police.

“You can do so by calling 101, quoting reference number 43200090463, or if you wish to remain 100 per cent anonymous, call the independent charity Crimestoppers on 0800 555 111.

“You can also make a report online.

“I would also urge the public if they see Olteanu, not to approach him, but to get in touch with police immediately on 999.”
