NA Haris is the Congress lawmaker from Shantinagar in central Bengaluru. His son has been in judicial custody for the past four months.
"The High Court has granted conditional bail to Nalapad on submitting Rs 2 lakh bond, and has been asked not to leave the city without the court's permission," a lawyer told reporters.
Mohammad Nalapad, 24, and six others were arrested after they surrendered on February 19, two days after they attacked a young man, Vidvat,following an argument at an upscale restaurant. Nalapad allegedly walked up to the man, who had his bandaged foot on a table while having his dinner. Nalapad allegedly asked him to remove it and "sit properly". When Vidvat refused, he was attacked by the group and beaten so badly that his eyes were swollen shut and his clothes were blood-soaked.
Nalapad's bail plea was earlier rejected by the High Court on March 14 and by a sessions court on March 2. He has been charged with attempt to murder.
Mr Haris, a three-time lawmaker from Shantinagar, termed bail for his son a gift from God.
"The family is relieved and we thank Allah for Nalapad's release from jail on bail," the lawmaker told reporters.
