A man has been charged with robbery after a 14-year-old boy had his mobile phone stolen from him in Duffield.
Shane Tomlinson, 19, of Belper, is alleged to have taken the phone during the incident on Meadow Vale at about 4pm on Friday, July 22.
A police spokeswoman said it was alleged the victim was punched in the stomach before the phone was taken.
Another 19-year-old man, also of Belper, was arrested by police on suspicion of robbery in the aftermath of the fracas.
He was questioned by officers but later released without charge.
The police spokeswoman said Tomlinson was due to appear before magistrates this week.
