A south-end community is debating whether extra safety measures are needed following the sexual assault of a senior by a mysterious serial rapist.

A 68-year-old woman was at home by herself in the Aspen Gardens neighbourhood early Saturday when a man entered her house.

Investigators say the woman was assaulted in her home, near 40th Avenue and 122nd Street, by a strange man wearing dark clothing.

Police said they believe the man may be behind three other attacks in the Garneau neighbourhood from this spring.

Aaron Dublenko, president of the Aspen Gardens community league, said they will hold a meeting soon to discuss whether things like a neighbourhood watch or citizen patrol are necessary.

"This is the time right now for communities to look at themselves," he said.

Some residents living in the south-end neighbourhood said they've already altered their activities to protect themselves against any attacks.

Elizabeth Harrison said she no longer walks her dog alone.

"I've always felt really safe in this neighbourhood," she said. "It's just weird when stuff like that happens."

Meanwhile, the Sexual Assault Centre of Edmonton has since pulled their safety tips section from their website.

Spokesperson Karen Dushinksi said their recommendations had the potential to give women a false sense of security.

"That's kind of an almost naive response, asking women to do something differently," she said. "In reality it's not women that need to do things differently, it's our communities."

Investigators describe the man as about 5'9 tall, with a stocky build, wearing dark clothing and a disguise on his face.
