I do not know how to report an incident witnessed around [a] federal prison at XA:45 am [on] DATE. [One] plane was actually chasing another plane a few hundred feet above the ground and literally a few yards apart over a residential neighborhood near Lakewood; Colorado. At the corner of Street and Street1. The tail plane was right on top of the other plane for a good 10 minutes before it veered off and let the 1st plane return to the BJC airport in Broomfield Area Colorado. Both planes were extremely low and this act was very scary to witness.
A concerned individual observer reported witnessing two small aircraft maneuvering erratically while flying too low over a residential neighborhood.
