LONDON, MARCH 5: A British police sergeant of Indian origin has been summarily dismissed from the force after he was found guilty of sending racist literature to ethnic minority officers and civilians staff, including himself.In one of the most unusual disciplinary cases in the metropolitan police, Sgt Gurpal Virdi was convicted after a four-week hearing.Virdi, 41, joined the force in 1982 and worked in the Ealing division, west London. He was alleged to have used the police computer system to create offensive letters, in December 1997 and January 1998. These were sent to Black or Asian officers and civilian staff, police said.For the second letter, it was stated that he logged on a computer using the password of a young White lady constable, on whom suspicion fell.Virdi, a Sikh who has been suspended on full pay since April 1998 has always denied sending the material and is expected to appeal against the tribunal decision.
