BBC reporter claims single women are not allowed to lodge in most hotels in Kano state

According to BBC reporter, Isa Sanusi who visited Kano recently, hotels in Kano state give out this slip to their guests to sign. Here is what he wrote:

"I was in Kano earlier this week to collect material for a feature I'm working on and checked into hotel where I was asked to sign this slip. Every guest at most hotels here are required to sign such statements because of random raids by the Hisbah - the city's Islamic police force. The Sharia officers search the hotels looking for single women, who they always assume are prostitutes".
