Police in India's western state of Rajasthan have been accused of delays in helping a man who was lynched for alleged cow smuggling and later died.

Rakbar, 31, was attacked, allegedly by a mob of cow vigilantes, on Friday.

It reportedly took police three hours to take him to the nearest hospital.

Hindus consider cows sacred and killing them is illegal in several states, including Rajasthan. So-called cow vigilantism has risen, aimed at protecting them from slaughter.

The issue has become a matter of fierce debate.

Congress party president Rahul Gandhi said the latest lynching was an example of PM Narendra Modi's "brutal New India". Mr Modi's Bharatiya Janata Party fired back, calling Mr Gandhi a "merchant of hate".

The latest incident occurred on Friday night in the town of Alwar.

Police were informed about the attack at 00:41 by Nawal Kishore Sharma, a member of a right-wing Hindu group. But hospital records show that Rakbar was brought to hospital only at 04:00.

Police say he died on the way to hospital, which was only five kilometres away.

"There are allegations that the policemen on duty took too long to take the victim to hospital," senior police official Rajendra Singh told BBC Hindi's Narayan Bareth. "We're currently investigating the matter."

The police have arrested three people who were allegedly part of the mob that attacked Rakbar.

But local lawmaker Gyan Dev Ahuja said the police were framing "innocent locals".

Mr Sharma told the BBC: "Rakbar died in police custody because of their carelessness and the police are unnecessarily blaming the group. How can it take the police so long to cover a distance of five to six kilometres?"

This is the third incident of alleged cow-vigilantism in Alwar in about a year.

One of the most high-profile incidents occurred when a dairy farmer, Pehlu Khan, was beaten to death by cow vigilantes affiliated with ring-wing Hindu groups.

Incidents of such vigilantism have become increasingly common in India, but police investigations have often led to acquittals.

However, in March 2018, a court in the northern state of Jharkhand for the first time sentenced 11 men to life in prison for lynching a Muslim meat trader.

It's a strange planet we live on.

So much nuisances over religion!. Strange indeed!
