An alleged drug dealer linked to at least seven overdoses on Staten Island, one of which was fatal, is among three people indicted in a drug bust.

Police say 38-year-old Cashorn McMaster sold heroin, cocaine and fentanyl across the borough.

He was arrested Wednesday as part of a 10-month-long probe by the NYPD.

He faces charges of first-degree criminal sale of a controlled substance and reckless endangerment.

McMaster and 32-year-old Amanda Martinez are also facing child endangerment charges for allegedly selling heroin while a child was present. 

Authorities also arrested 24-year-old Jahnell Wright in connection with the drug operation.

The three were arraigned Wednesday.
