DETECTIVES have stepped up their hunt for an armed robber who threatened a security guard at gunpoint.

It is understood the robber threatened the worker with a gun ­before making off with an unknown amount of money.

As reported in late editions of yesterday's Evening Times, a police probe is under way after the incident outside a shop in Uddingston, South Lanarkshire.

Officers were called to the scene in Old ­Edinburgh Road after 9am yesterday.

It is understood no-one was injured, although the security worker was left "shaken".

The exact amount stolen in the raid is not yet known.

Police said the investigation was at an ­"early stage".
