Guelph police say five people face over 30 charges combined in relation to a drug trafficking investigation that began in March.
The investigation led officers with the drug enforcement unit to a home near Edinburgh Road and Wellington Street on April 9 when a search warrant was carried out.
Police said they seized ammunition and replica guns, along with other weapons such as knives, axes, swords and a baton.
A variety of drugs were also found during the search including crystal meth, LSD and magic mushrooms, valued at around $2,500.
Police said five motorcycles, worth up to $20,000, were also seized including one that was reported stolen from Waterloo Region just a few days ago.
Those arrested include three men, a woman and a 16-year-old boy. They will all make court appearances later this year.
Police said the investigation is still ongoing.
