Four teenagers held in connection with Sheils murder

Police in the North are questioning four people in connection with the murder of Emmet Sheils in Derry last week.

Three male youths aged 16, 17 and 18 were detained after presenting themselves at a police station in the city yesterday afternoon.

An 18-year-old woman was also arrested last night.

Mr Sheils, aged 22, was shot dead early last Tuesday morning after apparently intervening in a planned attack by masked men in the Creggan area.

Dissident republicans are being blamed.

Two men who voluntarily went to a police station several days ago have since been released without charge.
