Two robbers involved in mugging people on Leicester streets have been locked up.
The first robbery took place on January 12 at 3am, when a young man was walking along Melbourne Road, in Highfields.
He noticed three men in a car, including Luknoor Jahed (19) and Jawad Raja (18).
James bide-Thomas, prosecuting at Leicester Crown Court, said one of the men asked the man: "What are you looking at?"
He turned into a side street to avoid them, but they ended up confronting him and demanding property.
The victim was punched about 10 times by all three, who made off with his two bank cards, driving licence and two mobile phones, a Nokia and a Samsung.
Jahed bought a Renault Clio soon afterwards, but registered it in the robbery victim's name in order to conceal his own identity, the court heard.
Then, on January 27, two 16-year-old boys were robbed of their iPhone 5s in Hutchinson Walk, near Moat Community College, in the city, at 6.15pm.
One victim was pushed against a wall and hit on the left thigh four or five times with a nine-inch spanner.
The victims' pockets were searched by Raja and another male while Jahed waited in his car, which drove them away.
Mr Bide Thomas said: "About 15 minutes later, Jahed's Clio was stopped and the iPhones were recovered from a third defendant, Mohammed Khan, 17, who was a passenger."
A Nokia phone belonging to the first victim was also recovered.
Raja, of Bartholomew Street, Highfields, was given a three year detention sentence.
Jahed, of Atlas Close, Highfields, was sentenced to two years' detention, as he played a lesser role as driver when the two 16-year-olds were robbed.
Raja and Jahed admitted robbing all three victims, in a joint enterprise.
Khan, of Barnard Close, Highfields, admitted three counts of handling stolen phones and was given a two-year youth rehabilitation order, with supervision, and 150 hours of unpaid work.
Recorder Paul Atkinson said: "The message has been going out from the courts for many years that those who try to relieve people of their mobile phones by night with violence will be punished.
"It's a pity that on the streets of Leicester that message does not seem to have got home.
"It's prevalent and in some quarters seems to attract some kind of street credibility.
"If your friends think like that then they're not friends at all.
"These were revolting and cowardly offences and the sooner it's stamped out, the better."
He told Khan: "You're in a different position, for handling the proceeds of the robberies.
"You may be very close to the offences, but you're not convicted of them.
"I view with considerable suspicion the circumstances.
"You can count yourself lucky you're going out through the front door of the court."
In mitigation, defence counsel asked for credit for their clients' guilty pleas.
They said the defendants now regretted their actions and offered apologies to the victims.
They had not appreciated the seriousness of their actions at the time, the court was told.
