Armed police searched an area of Primrose Hill last night following a shop robbery in Netherthong.
A police video van and plain clothed officers and gun-carrying police could be seen at Cross Lane last night at around 8pm.
The road was closed and the police helicopter was also hovering over the area.
Police confirmed the police presence was linked to 'arrest enquires' following an earlier armed robbery at the Londis shop at Town Gate, Netherthong.
A masked gunman entered the shop and demanded cash before fleeing.
The female shop worker was shaken but uninjured.
Police confirmed no arrests have been made and enquires are ongoing.
Anyone with information should contact police on 101.
