A young man, who was part of a group of youths who rode through an Asda store in Brighton and frightened customers and staff, has been fined. Keith Mujuru, 19, unemployed, of Law Street in Southwark, London, admitted in court to dangerous cycling and using threatening or abusive words or behaviour likely to cause harassment, alarm or distress. It follows the incident on June 23 at the store in Brighton Marina when police responded to reports of threats being made by youths at the store. DCI Mike Ashcroft said: "The behaviour of Mujuru and the other youths that afternoon was totally unacceptable. "They came down from London and decided to cycle through the store frightening customers and staff, film it and put it on social media. "We worked closely with our colleagues at the Metropolitan Police in order to fully investigate these offences. "We will not tolerate this type of threatening and anti-social behaviour in our community." Mujuru was fined £440 for dangerous cycling and another £440 for using threatening or abusive words or behaviour.
