So was it a UFO or not?

That's what a lot of Britons are wondering after the U.K.'s biggest-selling newspaper reported that a police helicopter in Wales had chased a flying saucer — and the police responded by giving their own, much less dramatic account.

"Stunned police gave chase to a UFO after it attacked their helicopter near a military base," the Sun tabloid breathlessly recounted in its Friday edition. "The mystery aircraft zoomed straight at the chopper as the three-man cop crew prepared to land."

The incident apparently happened in the early morning of June 8 near Cardiff as the chopper was waiting to land at the St. Athan RAF base.

"The pilot banked sharply to avoid being hit, then launched into a high-speed pursuit," the Sun said "But he was forced to give up the chase as the helicopter's fuel ran low — and the UFO escaped."

The cops admitted the incident much more dryly: "South Wales Police can confirm its air support unit sighted an unusual aircraft. This was reported to the relevant authorities for their investigation."

The police denied there had been an attack, a pursuit or any danger to the helicopter's crew.
