Two persons were robbed by a six-member gang in separate incidents on Yamuna Expressway in Uttar Pradesh's Mathura district, police said on Thursday.
The gang had placed sharp objects on the expressway in a bid to deflate the tyres of vehicles passing through it.
On Wednesday, Vikram Gupta and Prateek Shukla became the victims of the gang. When they stopped their vehicles after a flat tyre, the robbers decamped with the valuables and cash kept in the vehicles, the police said.
Four police teams are looking for the suspects, said DIG/SSP Shalabh Mathur.

Later, the same gang robbed Shukla of Rs 13,000 cash and a mobile phone. Shukla was on his way to Kanpur from Noida, the SP said.
