From the March 2003 FHM:
Helicopter Lands in Home
Where: Cardiff
When: April 2000
Speed at point of carnage: 80 mph(ish)
The story: With both eyes locked on a joyrider roaring down the M4, the Welsh constabulary cleverly guided their prized £2.5m Dyfed-Powys Police chopper straight through the eaves of a Cardiff semi-detached house. The RAF managed to successfully remove it using a massive Chinook helicopter, but Mr Patterson - the house owner - suffered post traumatic stress syndrome and was unable to return to work. The poor sod.
Compared to the actual AAIB report:

Well, FHM got the date right, I guess that's a start.
If I was the pilot, I think I'd be on to my lawyers.
