A fake caution mail led to the Mumbai Police investigating an international human trafficking racket being run from the US by an Indian and a Pakistani national based there.

Mankhurd police recently received an email which said that six Indian nationals along with a Pakistani woman were going to leave for Dubai where they will be meeting an IS (Islamic State) handler.

The mail also stated that the IS handler will then give them some fake passports with the help of which they will travel to Pakistan to undergo terror training. Once the training is complete, the seven will leave for Dubai and then come back to India to carry out terror attacks across the country.

The email was sent by one Rizwan Sayed and also had details of names, passport numbers of the seven people and their residential addresses.

Syed is a Pakistani national and worked with, Ranish Sultan Dawa, an Indian national, in the US. The two reportedly ran an agency that helped people in getting US visas.

Police started verifying the details and found that the six Indians mentioned in the email were trying to go to the US and had relatives over there.

Investigation revealed that as official Visas were difficult to be processed and work visas weren't being issued to them, they came in touch with Rizwan Sayed who charged a premium amount of around Rs 20 to 25 lakhs per person to illegally help them move to the US.

It is suspected that Sayed wanted to dupe the seven people and was unable to deliver on his commitment following which he tried pulling this theory to frame the seven people in a fake terror case.

The investigations have brought to light an illegal human trafficking nexus and the Mumbai Police has communicated about the same to the central agencies.
