3 men on bike using fake medical emergency scam (UPI fraud)

I was standing at a bus stop when three men on a bike approached me and said they had an urgent medical emergency and needed money for blood/hospital. They pressured me emotionally and promised to return the money immediately with a small extra amount. Under pressure, I sent ₹2000 via UPI. After receiving the payment, they left quickly and did not return the money. One of them gave a missed call to make it seem trustworthy, but there has been no response since. I later found that this is a repeated scam pattern used on multiple people. Please be careful and do not send money to strangers in such situations.
