A man threatened a petrol station attendant with a knife before making off with a three-figure sum of money.

The suspect entered the Esso Garage in Glasgow's Ibrox area at around 5.30am on Saturday armed with a knife.

He then threatened the man working at the Broomloan Road premises, demanding money from the till.

The member of staff was uninjured but police said he was left badly shaken by the incident.

Detective sergeant Peter Sharp said: "Enquiries are ongoing in the local area to trace the man responsible."

The suspect is described as wearing a blue jacket with a red scarf, blue jeans, white trainers and an orange baseball cap.

Anyone with information relating to the incident is asked to call the police on 101.
