The police department in Massachusetts said the incident took place at a Walmart on August 15 around 7:10 p.m.
The suspect, whom the victim had never seen before, took an item out of his hand and then gave him a hug.
“Just giving you a Covid hug. You now have Covid,” the suspect said before laughing and walking away, according to the Springfield Police Department.
The victim is a cancer survivor, the police department said, adding that the suspect did the same thing to several other customers.
The department is asking that anyone with information contact the detective bureau.
