The accident took place near GT Karnal Road, which was deserted at the late hour.
Luckily, he found an auto and when the aut driver saw his condition, he drove like a maniac and took him to Max Hospital in Shalimar Bagh.
Gupta reached the hospital at 3 am and it took a series of surgeries to reattach his arm.
He also had a head injury for which he was simultaneously treated and was under the care of the hospital for the next three weeks.
Gupta can already move his arm a bit and plans to do his MBA next year.
