Manjhi visited Asian Heart Hospital at Mumbai and met Lalu Prasad, an official release said here.
The Bihar Chief Minister wished him early recovery after heart operation.
Bihar minister Mahachandra Prasad Singh and JD(U) General Secretary Shailendra Prasad accompanied Manjhi when he met Prasad.
Manjhi visited Prasad a day after his predecessor Nitish Kumar had paid a visit to RJD president at the hospital in Mumbai.
Ever since the alliance between RJD and JD(U) clicked in the recent bypoll winning 6 out of 10 seats, there is greater display of bonhomie between leaders of the two parties.
