According to tradition, people visit the shrine, which dates back to the 1800s, to pray for children. In Pakistan, microcephalics babies born with abnormally small heads are known as 'rats' and credited with god-like powers. Believers will give them money in the hope of blessings, but unscrupulous gangs of beggars are now exploiting this ancient tradition for their own ends. They kidnap young 'rat' children - or frighten parents into handing them over and then force them into a lifetime of begging on the streets. They are lucrative so much so that some people allege that normal babies are being deliberately deformed to look like microcephalics.There may be as many as 10,000 of these people, most in the province of Punjab and the city of Gujrat.”Rat children" grow up with mental and physical handicaps Experts say they are being deliberately deformed by criminal gangs operating around the shrine who then use them for begging. they use iron rings which are placed on the baby's head to stop it growing.
