AN armed robber snatched about £100 from an open till during a raid on a pub.
The man burst into the Engineers Arms in Seaham, and headed straight for the till, which was open, and grabbed about £100.
As he went to leave the South Crescent pub, bar staff challenged the man and he pulled a knife out of his pocket before running away.
Police said he did not directly threaten anyone with the weapon.
Detectives are now urging witnesses to come forward to help them trace the offender.
The robbery took place on Monday at about 6.40pm.
Anyone with information is asked to phone Durham Constabulary on 0345 6060 365 or Crimestoppers anonymously on 0800 555 111.
