The Office of the Telecommunications Authority and Police have seized three illicit decoders and are questioning three people after a raid in Sham Shui Po.

Some 37 smart cards and nine smart card programmers were also seized.

The sale, import, export, manufacture, offer for sale or let for hire of any unauthorised TV decoder warrants a $1 million fine and five years' jail. Users of such decoders will also be subject to civil court action by pay TV operators.
