Chinese authorities say they are investigating after one of the country's top police chiefs spent a day at a US consulate, state media reports.

Wang Lijun entered the consulate in Chengdu on Monday and left the following day, Xinhua news agency said.

The US State Department earlier confirmed Mr Wang had visited, fuelling speculation he had been seeking asylum.
