"We are afraid the same situation will occur again. They were moved to Abuja last time, but were never prosecuted," Gregory Yenlong told the Reuters news agency.

"As it is now, we hope those arrested will return to Jos where they can be prosecuted."

Justice demanded

In the aftermath of the clashes, Goodluck Jonathan, Nigeria's vice-president, pledged that the organisers would be brought to jutsice "no matter how highly placed".

The opposition Action Congress party has blamed local politicians for the violence, saying they helped stoke tensions in Jos.

"These politicians who aid and abet these destructive acts for their own selfish purpose have always worked behind the scenes to shield those behind the senseless orgy of killing, maiming and destruction," Lai Mohammed, the party's spokesman, said in a statement.

"If the federal government is sincere about ending the violence, it must start today by bringing those behind the latest crisis to book immediately."

Hundreds of troops were deployed to end the violence, which some locals said was sparked by Christian anger over the building of a mosque.

However, religious leaders have said that the violence owes more to the failure of local politicians to address ethnic differences
