The Ames Police Department issued a warning on Saturday morning via Facebook and Twitter in response to two alarming events near Campustown in the last week.

A woman reported an attempted sexual assault by two white males on Sunday morning near Lettie Street. This morning, another woman reported a sexual assault that took place on the 300 block of Ash Avenue. She said both were college-aged white males over 6 feet tall.

Police said they do not yet know if the two incidents are related, despite the similarities.

Ames Police Department advised “everyone to utilize the buddy system when out after dark and have a charged mobile phone with you to dial 911.”

The posts also requested anyone with information to contact the Ames Police Department at 515-239-5133 or to call the anonymous tip line at 515-239-5533.

“You may also contact Crime Stoppers of Central Iowa at 515-223-1400 or 1-800-452-1111. Online anonymous tips may be submitted to www.crimestoppersofcentraliowa.com or text a tip, Text “PCCS” plus your message to 274637 (CRIMES),” the posts said.

The posts said police are currently unable to release additional information, as the incidents are under investigation but said there was not much of a description in either case and that both women were walking alone when attacked.
