Probe: University chief 's final note not factual

A joint investigation has found that the final note left by Chengdu University's Party chief before taking his life lacks a factual basis, the Chengdu government information office said on Friday in a statement.

In Mao Hongtao's final post on WeChat Moments, he alleged that he had been subjected to "persecution and injustice" from the president of Chengdu University, Wang Qingyuan.

An investigation team was set up the same day by city authorities after Mao's body was found in a river on Oct 16. He committed suicide and died of drowning, the police said.
