The Waterloo Regional Police Service is investigating after a home invasion at a Borden Avenue residence that sent at least four men to hospital and left a trail of blood.

Police say they were called to the home shortly after 3 a.m. following reports of a disturbance. The occupants had apparently awoken to find multiple suspects in the home.

Neighbour Lloyd Henry says "We heard a bunch of commotion...We just felt at first it was kids going down the street."

At the scene police found several injured men and a trail of blood along Borden Avenue all the way to Weber Street.

Waterloo Regional Police spokesperson Olaf Heinzel says "We still have very much an active investigation underway…we're still trying to sort out what occurred and why."

Two men living at the home were taken to hospital with non life-threatening injuries. A third male was taken to a Hamilton hospital with serious injuries.

A Kitchener man who fled on foot was also treated in hospital for minor injuries before being taken into custody for questioning.

Police say they are investigating and looking for other suspects that may have been involved, but they believe it was a targeted act, either because of the address or the occupants.

Heinzel says "Police have been here before, but we still have to determine whether there's any connection to last night's events."

Anyone with information is asked to contact police at 519-650-8500 Ext. 4499 or Crime Stoppers at 1-800-222-8477.

Neighbourhood residents react

The trail of blood left on the sidewalk was a sight that left many local residents concerned.

Jessica lives in the area and says she was "Very shocked, very curious. I have a small son and he's not playing on the sidewalk today."

People who live and work nearby tell CTV News the house where the home invasion happened is busy at all times of the day and night.

Lisa lives in the neighbourhood and says "You see lots of traffic going in and out of the house. I mean you draw your own conclusions as to what that is, I mean we all have opinions."

Police do not believe there is any risk to the public. Heinzel says "The individual or individuals who came here, they came here for a reason."

While there may be no danger, residents are left to deal with a mess in what they call a normally good and safe neighbourhood.
