Halifax Regional Police say a robbery was foiled on a downtown street with the help of passing motorists.
Police say a group of five men were walking along Spring Garden Road around 11:30 p.m. Wednesday when they were approached by a group of six others who demanded their wallets and phones.
Police say the suspects began punching and kicking three of the victims when two motorists stopped to help.
The arrival of help caused the suspects to flee the scene.
Police brought in a dog team to search the area and say they later arrested three men who remain in custody on unrelated criminal matters.
One of the victims of the assault was treated for minor injuries and released.
