SPOKANE, Wash. -

It was a scary Monday evening for one family after their 6-year-old boy fell off a cliff overlooking Liberty Park.

"He fell at least 50 feet," Spokane Fire Department Lt. Gregory Borg said.

The Spokane Fire Department said a father and son were walking along the cliff just a little before 6 p.m. when suddenly the 6-year-old boy slipped and fell.

"We think he has a broken arm and a few bruises and scrapes and that's it," Lt. Borg said.

The boy was transferred to a nearby hospital with his dad. The dad told KXLY4 off-camera while waiting by the ambulance that he and his son were just exploring the area when his son got ahead of him. The boy slipped in the brush and fell down the bluff.

"His dad was freaking out," Johnny Billedeaux said.

The 14-year-old said he was sitting on the bluff watching the baseball game just a couple feet away and saw it happen. He called 911 immediately after.

"I heard somebody coming and I saw somebody slide on the side of me and it was that little boy and he fell," Billedeaux said.

He recalls seeing the boy sliding on his bottom and then disappearing. He then looked over the cliff and saw the boy lying on the ground. First responders showed up shortly after and took the boy away on a stretcher. He is expected to make a full recovery.
