He said that a Chinese woman and her Nepalese associate have also been arrested for allegedly paying Sharma large amounts of money routed through shell companies.
The police said Sharma was tasked with providing information on India-China boundary issues and other matters in recent years.
"Huge number of mobile phones, laptops and other incriminating/sensitive material have been recovered", the police said. The journalist Rajeev Sharma, a resident of Pitampura was earlier arrested for giving information to China. He has apparently been found to be in possession of classified defence documents and was allegedly spying for China.
Sanjeev Kumar Yadav, DCP, special cell, said the Chinese national had taken admission in Jamia Millia Islamia for a course in 2013.
Describing Sharma's six-day police remand as "mind-boggling", Press Council of India stated he wrote on "strategic affairs and may well have accessed routinely over-classified information on the Internet that is in the public domain".
His bail plea is listed for September 22, the police informed. A Chinese intelligence agent named Michael from Kunming city of China, who has been following the column of Sharma, contacted him through LinkedIn and invited him to Kunming for an interview in a Chinese media company. For this, he was allegedly offered 500 dollars per article. He had recently written a piece fo the Chinese newspaper Global Times. "Sharma had further meetings with George in Malaysia and again in Kunming", said Yadav.
During interrogation, Yadav said Sharma confessed about his involvement in procurement of secret/sensitive information and conveying the same to his Chinese handlers, namely Michael and George, based in Kunming in China through digital channels.
"Rajeev Sharma has received more than Rs 30 lakh from George in about 10 installments from January 2019 to September 2020 for the information provided by him. The current crisis is the biggest threat to normal ties between the two sides since 1962", he wrote.
In the article, he had highlighted that the two countries "have been engaged in a risky military standoff... which could wreck their economies and many precious things if the situation is not amicably eased".
Their common objective must be to build a better and peaceful future for their peoples and not a military buildup against one another.
Meanwhile, the Press Club of India has condemned Sharma's arrest.
"This is on account of the dubious track record of the Special Cell".
