The post mortem report contradicts assertions by Ram Manohar Lohia Hospital Medical Superintendent Dr T S Sidhu that Tomar had "no major external injury" except for some cuts and bruises or "(no) severe internal injuries".
The report said 47-year-old Tomar's third, fourth and fifth ribs on left side had fractures and there was "mid-calibaculur bleeding" at several places.
The cause of death reported by a Medical Board constituted by the hospital for the post mortem said, "myocardial infarction and its implication that could be precipitated by multiple ante-mortem (before death) injuries to neck and chest produced by blunt force impact."
Sources said effusion of blood was present in tissues and neck muscles and ante-mortem injuries were caused when the body suffered heavy blows from a blunt object.
Elaborating on the report, Additional Commissioner of Police (New Delhi) K C Dwivedi said it noted that there were injuries on his chest, neck, legs because of which he had a cardiac arrest and he died.
"He had a lot of injuries. His ribs had fractures. These multiple injuries aggravated his condition and led to cardiac arrest," Dwivedi said.
A controversy has erupted after two eye-witnesses, including a girl, claimed that Tomar, who died on Tuesday, was not attacked and he collapsed in front of them while chasing protesters at India Gate on Sunday.
Asked whether after the post mortem report, police would initiate action against doctors at RML, Dwivedi said he has no comments to offer as investigations were with Crime Branch. "I can't comment on doctors or eyewitnesses comments," he said.
Constable's death: Probe assigned to Crime Branch
After questions were raised over the cause of a Constable's death during violent protests last Sunday, the Delhi Police assigned its Crime Branch to investigate the case in which murder charges have been invoked.
Constable Subhash Tomar (47) died yesterday, three days after suffering injuries at India Gate where violence had erupted during protests against the gangrape of a 23-year-old girl in a moving bus in south Delhi on December 16, police had said.
"The case has been transfered to the Crime Branch," Delhi Police spokesperson Rajan Bhagat said. He did not provide reasons for transfering the case from New Delhi district police to the Crime Branch.
However, sources claimed that New Delhi district police will be busy in the coming days with regard to preparations for the Republic Day parade and maintaining law and order.
Questions were raised over the cause of Tomar's death with a journalism student, who claimed to be an eye-witness, countering the police version that the Constable was injured in the violence.
The police have slapped murder charges in the case. Earlier, eight persons were arrested on Monday on charges of attempt to murder.
Yesterday, Police Commissioner Neeraj Kumar had said that Tomar had suffered internal injuries in neck, chest and stomach and the police were waiting for post-mortem report for the exact cause of death.
