Three men badly hurt in day of violence

In one incident, a 16-year-old boy was attacked with a broken bottle in Wester Hailes on Sunday morning.

The victim was hit over the head with the bottle before being stabbed in the chest. The attacker was described as white, between 20 and 25, 5ft 10in tall, with short dark hair. He was wearing a blue T-shirt.

A police spokesman said: "While the victim's injuries are not life-threatening, he still suffered a serious chest wound. We are appealing for any information that can help us trace the suspect."

Earlier in the day, a 33-year-old man was targeted by four men while walking on Leopard Place towards London Road.

One of the gang punched him without warning, and the victim fell and hit his head on the pavement, police said. The men walked off towards Elm Row.

A Lothian and Borders Police spokesperson said: "This was a completely unprovoked attack which has left the victim seriously injured."

Another violent assault, on Monday morning, saw a man in his 20s seriously hurt in Leith.

Police said the victim suffered a serious head injury in the 1am attack.

Residents who live in the same block of flats as the victim claimed he had been beaten and stabbed in the building before being taken over the road and dumped on an old mattress next to a bin store in the Cable Wynd area.

He was rushed to the Edinburgh Royal Infirmary, and he remains in a critical condition.

Two men have been detained in connection with the incident, and police are appealing for witnesses to come forward.
