Police activity, a Hazardous Materials Response Team and paramedics on a St. John's street were due to a drug investigation, the Royal Newfoundland Constabulary confirmed Saturday.
A search warrant was issued for a residence on Beauford Place, a quiet cul-de-sac off Major's Path.
Combined Forces Special Enforcement Unit personnel in hazmat suits searched inside the home and in a vehicle that was parked in the driveway.
Saturday afternoon's activity drew a lot of attention from area residents, especially in light of the recent spate of opioid overdoses and a death on the Northeast Avalon. On Thursday, Eastern Health issued a warning to the public to be on high alert.
No other details are available at this time.
