Two young women have been targeted by thieves in "extremely frightening" knife-point robberies in Edinburgh.

Police are linking the two incidents that took place in the early hours of Sunday morning when a 20-year-old and 22-year-old were both targeted by two men.

The first incident took place when the 20-year-old was approached by two men, one on a bike and the other wearing a balaclava, in the Sciennes House Place area just after 1am.

She was threatened by the men who demanded she hand over handbag and phone.

After stealing the items the men made off towards the Causeywayside and Mayfield Road areas.

A second incident occurred around half an hour later in Drummond Street when the 22-year-old woman was approached by two men as she walked towards Roxburgh Street.

The men threatened her with a knife before making off towards Roxburgh Street with a bag containing the woman's laptop.

The suspects on both occasions are described as white and aged between late twenties and early forties.

One of the men is described as having a "straggly beard".

Detective Sergeant Dougal Begg of Corstorphine CID said: "These have been extremely frightening incidents for the victims and a thorough investigation of the events is now underway.

"We believe that these incidents are linked and would ask any members of the public who can help us identify those involved to come forward as soon as possible.

"The areas where both incidents happened are heavily populated with residential and business premises. I'd urge anyone with private CCTV, or who may have heard a disturbance in these areas in the early hours of this morning, to get in touch with officers immediately.

"These type of incidents are thankfully rare and officers are continuing to provide the necessary support to the victims. When out walking during the hours of darkness, always stick to well-lit paths, and if possible, use busier routes. If you feel uncomfortable alone, use a pre-booked licenced taxi or walk in a larger group with friends."
