TEHRAN (Reuters) -- Leading Iranian reformist Mohammad Ali Abtahi has been arrested, his office said.
Abtahi, a former vice president who backed reformist candidate Mehdi Karrubi in the disputed June 12 presidential election, was arrested early on June 16, the office said without giving further details.
Reformist sources said another prominent reformer, Said Hajjarian, was arrested on June 15.
Hajjarian is an ally of moderate Mir Hossein Musavi, who has formally appealed the result of the election that showed hard-line President Mahmud Ahmadinejad had won by a landslide.
Separately, the semi-official Fars news agency quoted a senior police official as saying some "antirevolutionary" people had been arrested with bomb material and weapons.
