A 15-year-old girl who police say was possibly sexually assaulted was discovered bound and gagged in a Baton Rouge drainage canal Tuesday.

Baton Rouge Police spokesman Cpl. L’Jean McKneely said passers-by on an overpass noticed the teenager in a ditch area near 11,000 N. 44th St. at 1:19 p.m.

The girl said she was attacked by three males, McKneely said, but he added he didn’t know the assailants’ ages.

“She was possibly sexually assaulted,” he said.

The teenager, of Baton Rouge, was reported missing as a runaway Monday night, McKneely said. She is being treated at a local hospital, he said.
