A political cartoonist who was jailed on sedition charges for drawings that mocked corruption in the Indian government has been released on bail.

Aseem Trivedi walked out of Mumbai's Arthur Road Jail on Wednesday after the local high court said there was no need for him to be held in prison.

Trivedi had earlier refused bail until all charges against him were dropped, but the local government has promised to review the charges.

He was arrested Sunday based on a political activist's complaint that his cartoons insulted the country. The arrest highlighted the government's increased sensitivity to criticism.

His cartoons mocked alleged rampant corruption among Indian politicians and were displayed at a Mumbai protest in December by anti-corruption crusader Anna Hazare.
