A police raid on a central Hamilton home last week yielded an “an array of drugs,” including crystal meth, ketamine and marijuana, and saw a man climb out a second floor window to evade arrest, police say.

Armed with a search warrant stemming from an “ongoing investigation,” officers with the Hamilton police’s Guns and Weapons Enforcement Unit entered a house on Arthur Avenue South around 7:55 p.m. on Friday, said police spokeswoman Debbie McGreal-Dinning.

She said the team arrested three males “without incident” and found another after he climbed out a second-floor window and jumped onto a neighbouring porch.

Inside the residence, police found “an array of drugs” including crystal meth, ketamine, the powerful painkiller hydromorphone and marijuana. They also seized 30 rounds of .22 calibre ammunition and five digital scales that were allegedly used for weighing drugs.

Three of the four men were released without charges. The other man, a 25-year-old Hamiltonian, faces numerous charges relating to the possession of illegal drugs, two breaches of a firearms ban and violating bail conditions.

He was held for a bail hearing.
