After several complaints of ongoing  illegal drug activity, Wareham detectives arrested a 25-year-old man, according to Police Chief John A. Walcek.

According to a release, detectives observed the man — later identified as Devyn Nickerson, of no certain address — acting suspiciously as he entered his car on Tuesday night around 6 p.m. near West Central Avenue in Onset. Detectives had been conducting surveillance of the area over the last two weeks.

Nearly 20 minutes after watching Nickerson enter the vehicle, officers pulled over the car. Police allege that, while approaching the vehicle, they observed Nickerson attempting to hide something.

After officers ordered Nickerson to step out of the car, they noticed a 9 millimeter semi-automatic handgun fully loaded on his hip. Police officers secured the firearm and immediately placed Nickerson under arrest. The female driver and a juvenile passenger were allowed to leave after speaking with the officers.

While transporting the suspect to the police station, officers located 62 grams of suspected fentanyl, 22 grams of suspected cocaine, multiple pills and $785 cash on him.

“This arrest is a direct result of citizen complaints of suspected drug dealing. The detective and patrol officers did an outstanding job in safely taking this man into custody,” said Walcek. “I cannot stress enough that the Wareham Police Department is here to improve the quality of life for this community by taking dangerous drugs and the people who deal them off of our streets.”

Nickerson was charged with carrying a loaded firearm without a license, possession of ammunition without a firearms identification card, Possession of a class E drug, trafficking in cocaine, and trafficking in more than 10 grams of fentanyl. He was held on $20,000 cash bail and was set to be arraigned in Wareham District Court on Wednesday morning.
