Arlington police are upping security at events around the city this weekend after a threat referencing the El Paso massacre was left at the construction site where the Texas Rangers' new stadium is being built.

Police spokeswoman Sgt. Karen Standback said the threat was reported Friday morning, but police don't believe it is credible.

"Of course, we're taking all precautions, so people will see increased security at several events throughout the city of Arlington this weekend to ensure the safety of everyone," she said.

Police Chief Will Johnson said the handwritten note was found inside a portable toilet at the construction site.

Reference a social media post circulating about Arlington. A handwritten note was located inside a porta potty at a construction site that caused alarm. We do not believe this threat is credible and no location was provided. You will see increased police presence this weekend. — Will Johnson (@ArlingtonChief) August 9, 2019

A Reddit post appearing to show a photo of the message shows writing on an orange surface that reads: "You think what happened in El Paso was bad. Just wait until what happens here on Saturday," followed by Saturday's date.

A gunman from Allen opened fire on a Walmart in El Paso last weekend, killing 22 people and wounding about two dozen others. He admitted to police that he was targeting Mexicans in the attack, and police attribute a racist, anti-immigrant manifesto posted online before the shooting to him.
