The City of Regina is warning people about a disturbing find at a pool over the weekend.

On Sunday, staff at the Dewdney pool in North Central Regina were preparing to open the facility for the day.  As they went to vacuum the pool, razor blades were discovered in the slide, and at the bottom of the pool.

Staff were able to remove all of the blades before the pool opened for the day, and any children arrived.

"The presence of the razor blades is the only indication that there had been anything that happened out of the ordinary," explained Chris Holden, director of community services, "there was no vandalism, there was no sign of forced entry or anything like that."

City staff were forced to check over all facilities in Regina, but no other razors were found.

The Regina Police Service is now investigating the find, and so far there are no clues as to who might have planted the blades.

"I don't know of another incident like that," said Elizabeth Popowich, speaking for police.  She stressed that investigators are taking the apparent attack very seriously.

The city currently employs a security company that checks over all pools throughout the night.  Holden said security didn't see anything out of the ordinary Saturday night, but that they have the ability to increase nightly checks on this particular pool.

People are clearly still making their way into the city-operated pool.  Those living in the neighbourhood of the Dewdney pool said it's not unusual to see people breaking into the pool at night.

Luckily in this case, no one was hurt by the razors.  Holden said that's thanks to the morning checks done by staff.

"There are times when we go in the morning and we have to clean up broken glass.  Sometimes it makes it on the bottom of the pool.  So we have processes that are fairly aggressive to make sure nothing is on the bottom of the pool, and that it's safe."

The city and police are now looking to the public for more information as they try to figure out who might be responsible for the planted blades.

Anyone with any information is asked to call 777-5600 or contact Crime Stoppers at 1-800-222-8477 (TIPS).
