The possibility of former Telecom Minister Dayanidhi Maran’s arrest in an illegal telephone exchange case increased on Monday with the Madras High court rejecting his anticipatory bail plea and asked him to surrender before the CBI within three days. Maran may move the Supreme Court against the High Court order, source said. The order, by Justice Vaidyanathan, was in response to the plea moved by the CBI requesting the High Court to cancel the anticipatory bail it had granted to Maran, grand nephew of DMK chief M Karunanidhi.
