Can't see the video? Go here.

The video shows a woman and dog walking up to the front door of the home. She knocks several times while no one answers. Police say the woman can be seen speaking to someone in her sleeve, and officers believe she's giving her partners the "all clear" that no one is home and they can then burglarize it.

Plano PD posted pictures of another incident involving these suspects and more details on social media, saying the suspects are using "newer model vans, SUVS or large passenger vehicles with paper tags."

Police say the spree may be targeting Asian households, but everyone should be aware and careful. Similar events have taken place in Coppell, Allen, Colleyville, Garland, Frisco, and Lewisville.

If you know these suspects, you're asked to call 911 or Crime Stoppers at 877-373-8477.
