A pair of WNBA stars pulled off a series of escalating pranks, ending with police showing up to their practice

• Las Vegas Aces teammates Kelsey Plum and Dearica Hamby have been waging a prank war on each other.
• Plum threw water balloons at Hamby during brunch, then Hamby pranked her back by painting her car.

A prank war between two WNBA stars took an unexpected turn when police officers arrived at their team's practice.

Las Vegas Aces teammates and close friends Kelsey Plum and Dearica Hamby have been pulling harmless, lighthearted stunts against one another for the past week. But as time went on, the pranks escalated and resulted in a third party calling the cops — who arrived at the Aces practice facility Wednesday ready to make an arrest in the middle of a training session.

Plum first kicked off the hijinks with some help from Hamby's daughter, Amaya, during a play date on June 3. Wielding water balloons, the pair snuck up on Hamby while she ate brunch with some friends at a nearby restaurant.

A clip Plum posted on Twitter shows Hamby looking stunned as her giggling teammate and daughter pelt her until she's soaked.

Of course, Hamby was determined to return the favor. So ahead of Las Vegas' practice on Wednesday, she and Amaya got up to no good in the parking lot outside the Aces' facilities.

The mother-daughter duo splashed Plum's shiny black Volkswagen sedan with neon green, blue, and pink paint. Hamby left a $20 bill under one of the windshield wipers and told Plum to "go get your car cleaned" in a video she filmed of the damage.

Her five-year-old accomplice confirmed that "yeah," she's guilty as she walked away with paint-stained hands and a big grin.

That's where things went awry. While Plum and Hamby were practicing with their team — the best in the league, for what it's worth — two police officers arrived looking for the culprit.

As it turns out, a stranger reported what had happened to Plum's car before the star point guard was able "to leave practice and be soooo shocked at what happened," as Hamby tweeted was her intention. Instead, the police were purportedly prepared to arrest her for vandalism.

Representatives for Las Vegas did not immediately respond to Insider's request for comment. But given the fact that Hamby tweeted out updates following the authorities' surprise appearance, it's safe to assume that Plum declined to press chargers.

Hamby, Plum, and the Aces next take the court Saturday. They'll travel to Los Angeles for a 9 p.m. ET matchup against the Sparks at Crypto.com Arena.
