NEW DELHI: The Supreme Court on Wednesday sought a response of the Delhi Police on pleas of NewsClick founder Prabir Purkayastha and its HR head Amit Chakravarty against their arrest under anti-terror law UAPA.

A bench of Justices BR Gavai and Prashant Kumar Mishra issued notice to the Delhi Police and sought its response by October 30 after senior advocates Kapil Sibal and Devadatt Kamat, appearing for Purkayastha and Chakravarty, respectively, said they are in jail and the pleas be heard early.

On October 16, the top court agreed to list the matter urgently after Sibal mentioned it before the bench headed by Chief Justice DY Chandrachud.

The CJI had asked Sibal to circulate the case papers and said he would take a call on an urgent listing of the matter.

The Delhi High Court had on October 13 dismissed their pleas against arrest and subsequent police remand in the case.

Both were arrested by the Special Cell of the Delhi Police on October 3.

They subsequently moved the high court challenging the arrest as well as the seven-day police custody and sought immediate release as interim relief.

The court, however, refused to grant them relief, saying there was no procedural infirmity or violation of the provisions of the Unlawful Activities (Prevention) Act in arresting them.

The trial court had on October 10 sent them to judicial custody for 10 days.

The city police have lodged cases against the two under the anti-terror law Unlawful Activities (Prevention) Act (UAPA) for allegedly receiving money to spread pro-China propaganda.

According to the FIR, a large amount of funds to the news portal allegedly came from China to "disrupt the sovereignty of India" and cause disaffection against the country.

It also alleged that Purkayastha conspired with a group -- People's Alliance for Democracy and Secularism (PADS) -- to sabotage the electoral process during the 2019 Lok Sabha polls.
