The Southeast Asian Press Alliance (Seapa) and Charter 2000, a Malaysian citizen's media initiative, have demanded an investigation into last Saturday's mob attack o­n Tempo news magazine's office in central Jakarta.

Some 200 people protested outside the office against an article in the March 3-9 edition of the magazine. During the incident, two senior editors were allegedly assaulted, while a reporter was injured.

Tempo had reported that contractor Tommy Winata had submitted a Rp53 billion renovation proposal to the Jakarta administration in January to build a business centre at Tanah Abang, which housed the region's largest textile market. Last week, the market burnt down.
