Four people are arrested after a drug bust in Westport.

On Friday, Westport Police executed a search warrant at a Senechal Street home, turning up Oxycodone, Clonazepam, $1,000 in cash, a digital scale, and cell phones. Two pitbull terriers were taken from the scene by Westport Animal Control.

Police immediately arrested 31-year-old Frank Hobbs and 33-year-old Melissa Tavares of that address.

During the booking process, somebody called one of the seized cell phones, and said they were interested in selling Adderall pills. Officers waited at the arranged meeting place, and arrested 18-year-old Justin Houston and his mother, 46-year-old Lisa Donahue, both of Fall River.
