Two people have been arrested in connection with three attempted robberies in Dundee on Sunday.
Police Scotland confirmed a 37-year-old man and a 47-year-old man have both been detained and are assisting police with their investigation.
It is understood the younger man had earlier been questioned by police but released pending further inquiries.
Two bookmakers and a grocery store were allegedly targeted by a knife-wielding robber on Sunday afternoon.

Eyewitnesses spoke of seeing a heavy police presence including officers with police dogs.
Police have said they believed all three incidents were linked.
No one was hurt in any of them.
Anyone with information is asked to call 101.
