The man who has tested positive for COVID-19 has been admitted to AIIMS.
When the man was in police custody, he fell sick and started vomiting. He was immediately rushed to the hospital where doctors suggested endoscopy. His COVID-19 test was also conducted. According to his medical report which came on Thursday evening, he has tested positive for COVID-19, a senior police officer said.
On the intervening night of June 2 and 3, the pilot was on his way to Indira Gandhi International Airport in his office cab from Faridabad when the men on two-wheelers intercepted the vehicle on IIT flyover and took his wallet which contained Rs 10,000 and other essential documents.
They robbed the pilot at gunpoint and attacked him with a knife when he resisted, police said. AMP TDS TDS
