The Delhi police has arrested two persons for breaching the security of Prime Minister Atal Bihari Vajpayee when he was travelling from the airport to his Race Course Road residence on Tuesday night.

Ashok Kumar and Dharen Singh, who were drunk, had driven into the sanitised area on Rao Tula Ram Marg as the prime minister's cavalcade was passing by.

The Special Protection Group personnel accompanying the prime minister fired at the car, a white Maruti-Esteem bearing registration number HR 26Q 0427, damaging its windshields.

The duo, however, managed to escape, but was picked up from Gurgaon, which is on the outskirts of Delhi, on Wednesday morning. Cases of rash and negligent driving and interfering in the working of public servants were registered against them at the Delhi cantonment police station.

The car was also seized, police sources said.

The ownership of the car has been traced to one Umesh, the sources said.

They said Kumar and Singh were with a lady, Neena alias Gurmeet, when the incident occurred.

The duo is being interrogated, they added.
