B S Yeddyurappa told reporters, "I am happy about it. People have been expecting his arrest since the past few days."
CM complicated the Karnataka police for their success in taking Abdul Nasser Madani into custody.
Yeddyurappa also thanked the Kerala government for its cooperation in getting him arrested.
The Karnataka police team, camping in Kollam since Aug 10, executed the non-bailable arrest warrant hours before a deadline set by a Bangalore court was to expire.
Madani was listed as 31st accused in the additional chargesheet in the Bangalore blasts, which left a woman dead and 20 others injured here on Jul 25, 2008.
