"The accused, Yadav, was arrested from the house of a relative where he was hiding," said Bangarmau station house officer (SHO) Amit Kumar Singh.
Yesterday, area councillor Sunil Bangarmau said if proper tests are done, at least 500 cases of HIV would come up.
"40 positive cases have been found. If proper tests are done, at least 500 cases would come up. It is being told that the people here used to go to a quack for treatment of diseases. He used a single syringe on all of them," said Bangarmau.
Health camps have been setup by the local health authorities to curtail the spread of HIV.
Uttar Pradesh Health Minister Sidharth Nath Singh had also assured an investigation in the connection. (ANI)
