City University postgraduate student Chen Jing has been jailed six months by Kowloon City Magistracy for offering a $10,000 bribe to an associate professor for questions and answers to a mathematics examination. Chen pleaded guilty to one count of offering an advantage.

She came to Hong Kong from Wuhan City in September and enrolled in a course offered by the university's mathematics department. A final examination for the course was scheduled for December 16. Ten days earlier, an associate professor found in his mailbox an envelope containing $10,000 cash.

The professor later received an email from an anonymous writer who claimed to be a student of the course and the person who deposited the money into his mailbox. Five days later, the professor received two other emails from the defendant, urging him to send her the examination questions and answers.

The professor reported the case to the Independent Commission Against Corruption, and arranged a meeting with the defendant yesterday at a cafe to let her view the examination papers. She identified herself as the anonymous writer and was arrested.
