Uttar Pradesh government Monday suspended four Government of Railway Police constables in connection with the Nauchandi Express train clash between a group of doctors and Police Armed Constabulary jawans near Moradabad.

The state home department has issued instructions to identify the PAC jawans involved in Sunday night's clash, official sources said in Lucknow.

Several doctors were injured in a clash with a group of PAC jawans in Allahabad-bound Meerut Nauchandi Express train near Moradabad in Uttar Pradesh, leading to strike by the medics in many medical colleges across the state, police sources said in Lucknow Monday.

The trouble started when a group of doctors, returning from Meerut after the PG Medical Entrance Examination, asked the PAC jawans to vacate the reserved seats in the sleeper compartment of the train Sunday night.

The PAC personnel, however, refused to vacate the S-3 coach and instead allegedly beat the doctors and some passengers, the sources said.

When the train reached Moradabad, more PAC personnel joined their colleagues and both the sides virtually fought a pitched battle in the running train, they added.

Several doctors suffered injuries, the sources said adding, the medics have alleged that five of their colleagues were thrown out of the moving train by the PAC men.

Additional Superintendent of Police, GRP, Rampur, Amitabh [Images] Yash said some of the doctors received serious injuries and were being treated in Moradabad and Meerut hospitals.

Yash said the PAC jawans had occupied the reserved seats in the train, but it was the doctors who first roughed them up leading to the trouble.

He denied the doctors' claims that five of their colleagues were missing as they had been thrown out of the moving train by the PAC men.

The agitated doctors stopped several trains at Rampur railway station demanding action against the PAC jawans.

The train traffic on Lucknow-Delhi section of the Northern Railway was consequently affected and several long distance trains, including the Lucknow Mail and Shaheed Express, were held up for several hours, the sources said.

Protesting the incident, doctors at Allahabad, Meerut and Gorakhpur medical colleges went on strike, the sources added.
