Mumbai: Ever wondered why one fails to avail a Tatkal train ticket. The Central Bureau of Investigation (CBI) has arrested four people involved in a multi-crore railway ticket booking fraud. The booking agents through fake user IDs book large number of Tatkal tickets within seconds from the IRCTC website and sell them to those in need at much higher prices.

A ticket agent is given only one user ID, but the accused accessed the IRCTC portal through a series of fake ID accounts. The accused used to carry out their business from Vadala suburb of Mumbai.

Meanwhile the police is looking into how the culprits acquired the software and what has been their exact earnings in the process.

A case of cheating and criminal conspiracy has been registered against the accused Mehtab Khan, Mahboob Malik, Shantaram alias Pappu Yadav and P Kumar Naga. The investigation agency suspects that the accused also violated the Information Technology Act 2000.

While Khan, Malik and Kumar have been sent to judicial custody till March 15, Pappu will remain in police custody till March 12. According to the enquiry, Malik had provided the software to Khan and Kumar after acquiring it from Pappu.

Pappu had taken the software from Salman Ahmad, a resident of Uttar Pradesh, who is yet to be arrested.
