Umar Ansari, the son of UP ganster Mukhtar Ansari, has claimed that his father was given slow poison in jail. Umar's statement came after Mukhtar Ansari died on cardiac arrest in Banda hospital on March 28.
The family has said it will approach the judiciary.
“I was not told anything from the administration side, I came to know about it through the media... But now the whole nation knows everything... I came to meet him two days ago, but I was not allowed…," Umar told news agency ANI.
Ansari's family had made these allegations earlier as well.
"We said earlier also and even today we will say the same about the allegation of giving slow poison. On March 19, he was poisoned in the dinner. We will move to the judiciary, we have full faith in it..." Umar Ansaru said.
A post-mortem on the gangster-turned-politician's body will be done on March 29.
Ansari's brother and Ghazipur MP Afzal Ansari had on Tuesday alleged that he was being subjected to "slow poisoning" in jail, a charge denied by the authorities.
According to a medical bulletin, Ansari was brought to the medical college around 8.25 pm on Thursday in an unconscious state after he had complained of vomiting. A team of nine doctors attended to him but he died of cardiac arrest, it stated.
Officials at the police headquarters in Lucknow said Ansari's post-mortem will be done in Banda and it will be videographed. The viscera will be preserved if needed, they said.
Earlier, Ansari was hospitalised for around 14 hours on Tuesday after he complained of abdominal pain.
