How did the leader of government’s opponents get away from the police?

Government officials say they will investigate just how three leaders of the anti-government protests managed to escape when police tried to surround their hotel Friday.
    One of the leaders climbed down three floors using a rope, and was rushed away by supporters thronging the building.
    Officials earlier Friday said the government is preparing to arrest people linked to clashes with security forces last Saturday that left 24 soldiers and protesters dead.
    The government says armed men infiltrated protester ranks and fired on troops trying to disperse a rally.
    The anti-government movement, led by the United Democratic Front against Dictatorship or UDD, demands that the Government call fresh elections. UDD supporters have held protests in Bangkok for more than a month.
    Thailand is facing its most severe political crisis in almost 20 years. Some parties in the governing coalition want to set a clear time frame for elections to ease tensions. But the government says it will only call elections once the political situation has cooled.
