Passers-by gave first aid to the two victims of a double stabbing that happened in Birmingham city centre this evening.
The Ambulance Service say a number of emergency calls were received from members of the public shortly before 6.00pm this evening.
Medics including two doctors and three ambulance crews arrived at the scene to find "excellent first aid being given by police and passers-by".
Both men suffered cardiac arrests despite "advanced life support" given to both victims by medics. The men believed to be in their 40s were pronounced dead at the scene.
One man was arrested minutes after the stabbings, of which police say there were "potentially hundreds of witnesses".
