Rome, January 3 - Police in Tuscany said 32 members of the Golden Drakes motorcycle gang were under investigation on Thursday, a week after police confiscated a huge cache of weapons from members of another gang in the central Italian region. The members, whom police called "violent people", are linked to an attack in Tuscany on July 13, 2011 outside a clubhouse of a rival motorcycle gang called the Smoking Wheels, in which five of its members were beaten with baseball bats and clubs. Police said the suspects, who varied in age from 30 to 60, made off with the leather jackets and motorcycle keys of several of the victims. The crackdown came just over a week after police in Tuscany uncovered a an arsenal of weapons at the homes of bikers in a gang called The Mongols. Weapons seized included machetes, swords, knives, brass knuckles, crossbows, spiked clubs, airsoft guns, bows and arrows, baseball bats and rifles, as well as handcuffs and a bullet-proof vest.
