of an uncle of one of them by Sena activists.
The arrests also sparked an outrage with Press Council of India chief Markandey Katju today demanding "immediate" action against police personnel involved.
While Dhada was arrested for the post, Dhada's friend Renu was arrested for 'liking' the post.
"Police arrested both of them under section 505(2) (statements creating or promoting enmity, hatred or ill-will between classes). Today, they were granted bail," their advocate Sudhir Gupta said.
The duo was arrested following a police complaint lodged by a local Sena leader.
After the comment was posted, a mob of nearly 40 Shiv Sainiks allegedly barged into Dhada's uncles's orthopaedic hospital at Palghar and vandalised the place yesterday.
However, no arrests were made in connection with the attack.
Some other tweets in support of the girls read: "Hatred of minorities, liberals is an epidemic on Twitter. Law shd be harsh on hatespeak not on democratic rights of 21 year olds!Cheerio" (@sagarikaghose) and "So the girl n frnd got arrested for posting stuff on FB did Shiv sainiks get arrested for destroying the doc's hospital?? #Mumbai #Balasaheb" (@SocoMumbai).
Last month, a businessman from Puducherry was arrested on the charge of posting "offensive" messages on social media targeting Union Finance Minister P Chidambaram's son Karti Chidambaram.
