The post mortem report of farmer Gajendra Singh says that he died from hanging, the Delhi Police confirmed on Friday.
"As per preliminary finding from post mortem report, death is due to hanging," Delhi Police Commissioner B.S. Bassi told the media.
He also said that Delhi Police is a part of the government and there was no infighting with anyone.
"We take all actions as per rule of law. All appropriate actions will be taken," he added.
Singh took the extreme step at an AAP rally at Jantar Mantar in New Delhi.
As per reports, a suicide note was found that revealed the farmer, who had three children, was banished from his house after his crop was damaged. He took the extreme step because he had no means of support his family.
Later, senior leaders of the AAP had accused the Delhi Police of being responsible for his death, alleging that the Centre is using the force as its puppet.
