Three men forced their way into a house and robbed a man of money after threatening him with weapons.

The 56-year-old answered the door of his home in McGregor Path in the Glenboig area of Coatbridge, North Lanarkshire, at about 9.35pm on Sunday when he was confronted by the group.

The men, two of them were armed with bladed weapons, then forced their way inside before escaping with a three-figure sum of cash, Police Scotland said.

Detective Sergeant Peter Lennon said: "Thankfully the man was not injured, however it was a very frightening experience for him, especially the fact that the men threatened him with weapons.

"At this time officers are checking CCTV and speaking to neighbours to glean information.

"It's a residential area, so it's possible that someone heard or saw something that will assist officers with their inquiries.

The suspects were all white and had scarves covering their faces.

One was described as 5ft 7ins, slim and wearing a dark hooded top. Another was 6ft, of heavy build and wearing an olive green hooded top.

Both men had Scottish accents.

Meanwhile, police in Edinburgh are investigating an armed robbery and assault in a stairwell in the Fountainbridge area.

A man, described as being in his late teens, was attacked in the entrance to a block of flats near the junction with Gilmore Park at about 5.25am on Sunday.

He had been walking along Fountainbridge heading towards Fountain Park when he became aware of two men following him closely from behind. They then grabbed him before pulling out knives.

The men walked him to a nearby common stair entrance and once inside, one of the attackers stole a sum of money and his mobile phone before both left on foot.

Detective Sergeant Robbie Wallace said: "The victim sustained no serious injuries, however this incident left him badly shaken.

"We're carrying out various lines of inquiry to trace both suspects and arrest them as quickly as possible."

He said officers believe both men might have been loitering near a Scotmid shop on Lothian Road shortly before the attack and appealed for anyone who remembers seeing them to get in touch.

They are described as white, aged between 20 and 40, about 5ft 10ins, with local accents.

One man had a skinny build and was wearing a dark jacket with the hood up which had a badge or crest on the left breast pocket while the other had a dark beard and was wearing a dark jacket with the hood up and black woolly gloves.

Later on Sunday, at around 8pm, a 32-year-old man was assaulted and robbed in the Oxgangs area of the capital.

He was walking on Oxgangs Road North when he became aware of two men.

One of them grabbed him from behind and threatened him with a sharp object, before dragging him to the ground.

The other man took his wallet and other items, and the pair ran off.

One of the men is described as white, with a local accent, aged between 20 to 30. He was wearing a black hooded top, which had white writing on it, and had his hood up.

Det Sgt Wallace said: "This was an unprovoked attack and we're asking anyone who saw anything suspicious in that area around that time to get in touch with us."
