Detective Sergeant Marshall said: “It was reported that two men entered a bookmakers in the area just before 5.45 pm.
“One of the men grabbed the female member of staff by the wrist and pushed her to the ground, where she was restrained, while the second man searched the premises.
“The two made off some minutes later with a sum of money.
“This was a terrifying experience for the victim who, while physically uninjured, has understandably been left badly shaken.
“One of the suspects is described as being approximately 5’ 11” in height, wearing a balaclava, black clothing and gloves.
“The second is also described as wearing dark clothing and gloves.
“This happened in a busy area, at a time of the evening when people were out and about.
“And I am appealing to anyone with information, or who may have noticed two men acting suspiciously, to contact us on 101 quoting reference number 1855 of 01/01/20.”
