Tushar Dave, head of digital services at GSTV, a Gujarati news channel run by Shreyansh Shah, said the ED detained Bahubali Shah in the early hours of Friday.
In a Facebook post, Dave said Shah was first taken to VS Hospital by the ED and then admitted to Zydus Hospital in the city after his health condition deteriorated.
The federal anti-money laundering agency has not yet issued any statement about the reasons behind its action.
A Gujarat Samachar employee said the ED detained Shah early on Friday, and he is in the hospital.
The Income Tax department searched the GSTV premises in Ahmedabad for nearly 36 hours. The ED raided the premises on Thursday evening, soon after I-T officials left, Dave said in another Facebook post.
Gujarat MLA and Congress state working president Jignesh Mevani slammed the ED, saying Gujarat Samachar and its owners are being targeted because, for the last 25 years, the newspaper has been publishing reports critical of the central government. PTI PJT PD NR
