A special police team will investigate an extortion case in which at least one property company was threatened with a bomb attack.
The Organised Crime and Triad Bureau will head the team, formed after the threat last month, with officers from the Criminal Intelligence Bureau assisting.
Police yesterday said detectives were investigating the matter after 'at least one' property company received an extortion letter.
'The writer threatened to launch a bomb attack if money was not paid,' a police source said, without revealing the names or number of companies threatened, or the amount demanded.
A separate source said the criminals had done nothing after sending the letter.
No traces of explosive or dangerous chemicals were found on the letter, which is being tested for fingerprints.
Investigators are refusing to comment on the case.
