Update:April fools! This was a marketing ploy by MetroParks of Butler County. Blow-up Martian figures appeared at the park Tuesday at Tylersville and Butler Warren roads with a sign promoting the availability of the park's new athletic fields.

Did an unidentified object touch down at Voice of America Park in West Chester?

Butler County park rangers are investigating after a passing motorist reported strange phenomena at the park Thursday morning.

The man, who asked to remain anonymous, told park officials he observed an "odd-shaped piece of construction equipment" near the park's new athletic fields while driving southbound on Butler Warren Road about 1:30 a.m. Thursday morning.

The man told officials he observed lights that appeared to be performing some type of work on the fields and found it odd, but hesitated to report the incident.

The man said he later drove by the fields again around 6:45 a.m. Thursday morning and stopped near the "equipment" and walked toward it.

He told officials he observed several workers with the vehicle, but as he approached, the workers "scrambled" into the vehicle, which then began to make an "odd humming/vibrating sound" and "disappeared completely," according to a release issued Sunday by MetroParks of Butler County.

The man provided a photograph he said he took of the object with his mobile phone before it "disappeared."

Park officials say no overnight work was scheduled to be performed at the fields Thursday. Rangers are now working with "multiple authorities" to determine whether the sighting is an "elaborate hoax" or a "legitimate phenomena," officials said.
