DENVER (AP) - Authorities have responded to four unrelated hot air balloon crashes in the metro Denver area that have left at least five people injured.
The Saturday morning accidents all happened within miles and about an hour of each other.
Arvada police spokeswoman Jill McGranahan says one person was injured when a balloon crashed into power lines and sparked a small brush fire.
Three people were in the basket when the balloon crashed near the intersection of state highways 72 and 93 at about 8 a.m. Saturday.
KUSA-TV reports another balloon went down in unincorporated Boulder County.
A third crash was reported in Louisville, but authorities say no one was injured. And a fourth balloon went down in the Rocky Flats area south of Boulder.
It was unclear if strong winds contributed to the crashes.
