A 15-year-old boy and a 13-year-old girl have been sentenced for killing an 80-year-old man out walking his dog in a park.Bhim Kohli died the day after he was assaulted in Franklin Park, yards from his home in Braunstone Town, Leicestershire, on 1 September last year.The boy, who racially abused Mr Kohli before slapping him in the face with a slider shoe, was sentenced to seven years in custody at Leicester Crown Court on Thursday.

The girl, who encouraged the assault and laughed as she filmed it on her phone, was given a youth rehabilitation order of three years and made subject to a six-month curfew. Both were convicted of manslaughter.During the hearing, prosecutor Harpreet Sandu KC said Mr Kohli was subjected to a "seven-and-a-half minute period of continuing aggression" while taking his dog Rocky for a walk.

The attack left Mr Kohli with three broken ribs and other fractures, but Mr Sandhu KC said the fatal injury was to his spinal cord, caused by a spine fracture.

Mr Kohli's children found him at the park "screaming out" in pain after the attack."Minerals and pigments are very similar," says Dr Gil, "so I borrowed the instrument and started looking for emerald green in books."

The next task was to speak to the physics department to build their own prototype.Dr Graham Bruce, senior research laboratory manager explains how it works.
