A 43-year-old man has been arrested for allegedly throwing bottles into the Roaring Fork River for months.
The suspect, Ricardo Maestrino Parras-Membreno, was arrested Friday morning.
The bottles began showing up in the Roaring Fork on January 24.
Police said 74 bottles have been found in the river since then.
Authorities said the bottles have been filled with corrosive, flammable materials that are hazardous to people's health.
Basalt Police Chief Greg Knott said his officers set up cameras near the area where the bottles were being found.
Knott said those cameras got good pictures of the suspect as he was throwing bottles into the river.
After working leads, officers set up an undercover operation and witnessed Parras-Membreno throwing more bottles into the water Friday morning.
Officers moved in and quickly arrested Parras-Membreno.
Later in the day, deputies from the Pitkin County Sheriff's Office, and other agencies, executed a search warrant at Parras-Membreno's home in the Roaring Fork Mobile Home Park.
Parras-Membreno is being held in the Pitkin County jail.
