The family of a teenager killed in a suspected gangland shooting has called on the community to provide police with information.
Kadeem Blackwood was walking with friends in the Sunny Hill area of Derby when they got in to an argument with another group of men and the 15-year-old was shot in the chest.
Police arrested a 19-year-old man on suspicion of murdering the teenager shortly after 9.15pm on Tuesday in Caxton Street.
A statement released by the family said: "We are distressed about the loss of our precious young boy and we ask members of the community to offer the police any assistance they can.
"This is an extremely traumatic time and we are too upset to comment further."
Detectives said a post-mortem was due to take place. Officers have also met community leaders to discuss the shooting.
Assistant Chief Constable Peter Goodman said: "We are now gaining a clearer picture of what happened that night. We understand that Kadeem was walking through the park with a group of friends when they were approached by another group of males.
"Some sort or argument occurred and a shot was fired. At which stage, a number of males involved in the incident ran off."
He added: "Several people have come forward with information and we are grateful for their help. However, we are still asking for people to contact us if they saw or heard anything that night, or if they have any other information which may assist us.
"We urge the community to stand up and be counted."
