A robber who agreed to let one of his victims save photos of his dying dog before he stole his phone has been jailed.

Derbyshire Police said Remar Junor carried out three robberies and two attempted robberies in Littleover and Mickleover during a three-day period in August.

Officers said after being ordered to hand over his phone in Sunnydale Park, one victim begged to be allowed to save photos of his dog as it only had months to live, to which Junor said: "Don't tell me that, why did I choose you?"

The 22-year-old, of Sapperton Close, Littleover, was jailed for three years and six months at Derby Crown Court on Monday after admitting three counts of robbery and two counts of attempted robbery.

Police said between 5 and 7 August, Junor approached numerous people on foot or by bike and struck up conversations about their mobile phones before threatening them and stealing, or attempting to steal, the devices.

Junor's victims believed he may have had a knife on him during the robberies as he threatened to pull out a weapon on them or showed them what appeared to be a knife handle concealed in his pocket, officers added.

A public appeal for information was issued along with a picture of the suspect, which resulted in him being identified and arrested.

PC Stephanie Merrick, of Derbyshire Police, said: "Junor subjected each victim to a terrifying ordeal in which they felt their personal safety was at risk before stealing or attempting to steal from them.

"We are pleased that this dangerous robber has been taken off our streets and been given a lengthy jail sentence."
