He allegedly assaulted the representative of the China Africa Development Fund, Mr Lui Jie.
“I can confirm that the assault was reported at the station,” said airport police chief Joseph Ole Tito.
The alleged attack took place at the baggage hall where Mr Lui was awaiting a delegation from the Chinese National Tourism Administration, flying in to promote tourism by the Chinese to Kenya.
Mr Waluke is said to have arrived at the airport at around 4.30pm in the company of Budalangi MP Ababu Namwamba and North Mugirango MP Charles Mon’gare. It is then that the MPs confronted Mr Lui, demanding to know why and how he had accessed a restricted area. They started taking photographs of the official before Mr Waluke, a retired major, allegedly slapped Mr Lui on the left eye and threw away a bouquet of flowers to be handed to the head of the delegation, Mr Wang Zhifa.
Mr Namwamba later admitted that they confronted the official but denied allegations of assault. He said that they had just arrived from Zambia when they spotted three men in the restricted area of the airport.
“When we alighted we spotted the Chinese officials at a restricted area without any security officer. It drew our attention given the high cases of insecurity in the country,” he said.
