Police say the raid of a suspected fentanyl pill mill Thursday was near another day care service.

This latest bust comes after two other other locations were raided in the past two months with one of them run out of a day care. The suspected Belmont pill mill is right next to another day care on Beaumont Avenue.

Four people are now in custody. Law enforcement officials say fentanyl and two industrial pill presses were discovered in the two-story home. The raid took place right next door to a community day care, making this the third fentanyl-related incident in the Bronx within the last three weeks.

Law enforcement officials say the amount of fentanyl discovered in Belmont is still unknown. No children were inside the home during the raid.
