Lahore: Pakistan's opposition leader cricketer-turned-politician Imran Khan surfaced at a student demonstration against emergency rule Wednesday.

His party said he was promptly detained by police.

Some 200 students cheered wildly and lifted Khan into the air when he got out of a car on a university campus in the eastern city of Lahore.

"Then some people came and took him away. He was on my shoulders when they grabbed him," Faisal Naim, a student said.

Naim said he couldn't identify the men in plainclothes who hustled Khan into a nearby building.

But Talath Naqvi, a spokeswoman for a local women's wing of Khan's party, said Khan was being held by police.

Khan, a former cricketing legend who leads a small but outspoken opposition party, went into hiding after President Gen. Pervez Musharraf declared a state of emergency on Nov. 3 and began rounding up opposition activists.

Khan gave a series of media interviews at secret locations in Lahore before deciding to join students protesting against Musharraf's assumption of emergency powers at the University of Punjab.

He was the only one of Musharraf's most outspoken critics not in detention or exile.
