Islamic police in northern Nigeria are threatening to arrest drivers of motorized rickshaws for wearing pants cut off below the knee and sleeveless T-shirts. They say that's indecent.

Spokesman Yusuf Yola of the Hisbah board in Kano state says they will also arrest drivers of the three-wheeled vehicles who carry men and women together.

He told The Associated Press on Monday that they are deploying 10,000 officers to ensure the cabbies comply with the state's Shariah laws that ban indecent dress and mixing the sexes on public transport.

He said Christians living in Kano state also are obliged to comply.

Nine of Nigeria's 37 states have introduced Shariah law since 2000 as some Muslims have become more fundamentalist. But the law is interpreted and enforced differently from state to state.
