The Central Bureau of Investigation received a setback in the Andhra Pradesh high court on Thursday when the court rejected its petition on extension of custody of YSR Congress party president Y S Jaganmohan Reddy in connection with his alleged illegal investments case.

As the five-day custody of Jagan came to an end on Thursday, the CBI filed a lunch motion petition in the high court seeking his custody for another three days to interrogate him in the case.

The CBI authorities said they had asked Jagan’s close aide Vijay Sai Reddy for interrogation in the same case on June 9 and 10 and they wanted to grill Jagan along with Sai Reddy.

The court wondered why the CBI was in so much hurry to get the extension of custody for Jagan.

“The lunch motion petitions are not meant for seeking custody of under-trials. Only emergency cases can be dealt with by the court during the lunch period. The CBI can file the petition on Friday,” the court said.

The CBI will now file the supplementary petition on Friday. It is not known whether it had gained any credible information from Jagan during the five-day custody.
