PRAYAGRAJ, Aug. 11 -- Police here have begun tracing the people who allegedly travelled in a fleet of private vehicles alongside the prison convoy carrying Umar Ahmed from Lucknow to Prayagraj under police custody to attend the funeral of his younger brother, Abaan Ahmed, son of slain gangster-politician Atiq Ahmed. Police are examining vehicle registration numbers and CCTV footage to establish who joined the convoy and who coordinated its movement. The investigation follows FIRs registered over allegations of breaking toll barriers, misbehaving with toll plaza staff and attempting to run over employees at toll plazas in Nawabganj and Hathigawan. According to police sources, the FIR lodged at Nawabganj police station mentions 10 vehicles registered in Prayagraj, nine in Lucknow, and one each in Azamgarh, Bareilly, Gorakhpur, Jhansi and Delhi, besides several unidentified vehicles. Police have identified some vehicle owners through registration numbers and started questioning them. Investigators are seeking to establish who was driving the vehicles and who the passengers were at the time of the incidents. They are also examining whether the vehicles accompanied Umar's convoy from Lucknow or joined it at different points on the route to Prayagraj. The probe is also focused on determining the relationship between the occupants of the private vehicles and why they followed the prison convoy during the journey. Police are questioning vehicle owners about who informed them about the trip and why they joined the convoy. Investigators are also trying to establish who coordinated or directed the movement of the large number of private vehicles from Lucknow to Prayagraj. Mobile phone location data and communication records may also be examined to establish links among those involved and reconstruct the sequence of events. "The accused are being identified based on CCTV footage and vehicle registration numbers. Legal action will be taken against those found involved based on evidence," said Kuldeep Singh Gunawat, DCP Ganganagar. Meanwhile, two of the three people injured in the recent road accident near Jhansi have been referred to Delhi for advanced medical treatment. The accident claimed the lives of Aban Ahmed and Sonu Khan, while three others were admitted to a private hospital in Prayagraj by their family members. Umar Ahmed and Zaid were later shifted to Delhi due to the seriousness of their injuries....
