Three held after tycoon's fatal stabbing

Police are questioning the alleged killers of a multi-millionaire who was stabbed to death in an apparent botched kidnapping.

Haidian district police said four men killed the entrepreneur, who had a net worth of 100 million yuan, on Thursday afternoon. Investigators believe the men were trying to kidnap him from the parking lot of a Haidian shopping mall at the time.

One suspect is believed to have killed himself on the spot when the bid failed. Three other men were arrested within 24 hours of the murder.
