UK: Suspects arrested in boy's killing

Police said four more people were arrested Friday in connection with the killing of an 11-year-old boy whose shooting death has sparked debate on Britain's gun laws.

Police also urged a witness who had called a "hot line" a week ago with information about the shooting to identify himself and come forward to be interviewed.

Rhys Jones was shot in the neck Aug. 22 as he returned home from playing soccer in Liverpool, northwest England. Police believe he may have been the unintended victim of gang warfare.

The death shocked Britain, where handguns are illegal and gun crime is fairly rare. A string of high-profile shootings and stabbings involving children has raised concerns about guns and gang violence in the country.

The four detained for questioning Friday are two men, aged 20 and 24, and two boys, aged 17 and 16, all from the Liverpool area.

The arrests raised to 15 the number of people who have been taken into custody in the case. The other 11, most of them teenagers, have been questioned and released on bail or freed without charge, police said.
