Killer on the run after man stabbed to death in Adelaide driveway

A man is on the run after stabbing another man to death in a driveway in Adelaide's inner-north. 

A man, believed to be aged in his 20s, was discovered seriously injured outside a block of flats on Blight St in Ridleyton around 11pm yesterday. 

Paramedics worked on the man but he died at the scene.

Police are speaking to a number of witnesses and do not believe the pair were known to each other.  

More to come.
