COLOMBO: An employee says an unidentified gang has attacked the head office of a private broadcasting company in Sri Lanka. Three employees were injured in the second attack on the broadcaster in just over a year. Shevan Daniel, an employee of Maharaja Organisation, says about 200 people suddenly gathered today outside the office in Colombo and threw stones at the building. Daniel said he did not know who the attackers were or what their motive may have been. Maharaja Organisation has three televisi-on and four radio channels. Last year, a group of armed men attacked its studio and transmission compound, tossing and grenades, spraying the building with gunfire.
