K.N. Tripathy of the Congress was Friday inducted as a minister in Jhakhand's Hemant Soren government, replacing one who had been sacked.
He was administered the oath of office and secrecy by Governor Syed Ahmad at the Raj Bhawan Friday evening.
Tripathy, a first-time legislator, was made minister after Chandrashekhar Dubey, another Congressman, was sacked Wednesday.
Dubey had a few days ago told media that Soren was the "most corrupt chief minister in the history of Jharkhand".
The Jharkhand assembly witnessed pandemonium Thursday and Friday over Dubey's allegation against Soren.
Jharkhand can have a maximum of 12 ministers, including the chief minister.
