One of China's top police chiefs, Wang Lijun, had arranged talks with British diplomats hours before fleeing to a US mission, the BBC has learnt.
In recent days it has been claimed that Wang Lijun had concerns that British citizen, Neil Heywood, who died in Chongqing last year, did not die accidentally.
The BBC's Damian Grammaticas, who is in Beijing, says the biggest political scandal to engulf China has just developed another twist.
