"Thank you god for always showering us with your grace and blessings. Today is a big day for us... Salman Khan. Thank you to all bhais and the family's well-wishers for your prayers, support, love and best wishes. This wouldn't have been possible without you," Arpita posted on her Twitter page.
The Rajasthan High Court on Monday acquitted Salman in two 18-year-old chinkara poaching cases.
Salman had appealed before the Jodhpur bench of the high court challenging a lower court verdict in 2006 handing him a one and five-year term in the two separate cases of poaching.
Salman and the state government had appealed before the high court challenging the lower court's verdicts on various grounds.
On Monday, Justice Nirmaljit Kaur while allowing Salman's appeal, acquitted him of all charges and also dismissed the state government appeal for enhancing the sentences.
The hearing was completed in the last week of May and the order reserved.
Salman was accused of killing chinkaras in two separate incidents.
One animal was said to have been killed at Bhawad on the outskirts of Jodhpur on September 26, 1998 and the other at Ghoda Farms on September 28, 1998. He was shooting for the film "Hum Saath Saath Hain" at that time.
Salman was earlier lodged in the Jodhpur jail over the cases.
Salman's sister Alvira was present in the jam packed court room when the judgment was pronounced.
However, no official comment has been released from the actor's side.
