Raveena said the incident took place here on Friday, when her in-laws got stuck in a traffic jam and suddenly her father-in-law started feeling unwell.
In a series of posts on Twitter on Sunday, Raveena shared: `My faith in humanity gets restored every time I feel it has dipped beyond repair. My in-laws were on their way to see a movie. When my father-in-law felt restless and couldn't breathe, the driver raced towards Lilavati hospital.
`But they got stuck in a jam at the junction near Cheap Jack, until a brave soul, a girl driving next lane saw my mother-in-law trying to massage dad's heart. She jumped out of her car realising emergency, cleared the traffic single-handed allowing them to rush to the hospital.
`My father-in-law was in full praise of her last night (Saturday) and says that if not for her, things would have been fatal. This happened on December 18.`
The `Dulhe Raja` actress said her father-in-law was now fine and recovering well.
`Thank you all for your wishes. Yes he's fine and bounced back strong,` she added.
