No foul play has been suspected in an incident where a woman plunged to death from a roller coaster at the Six Flags Over Texas amusement park in Arlington, Texas, authorities said on Saturday.

The accident occurred on Friday when Rosy Esparza, who was on the ride with her daughter and son-in-law, fell from the roller coaster allegedly because her safety harness was not secured properly. This was Esparza’s first visit to the amusement park.

"At this point of the investigation, it does not appear there was any foul play or criminality associated with this tragic incident," a statement released by the Arlington Police Department, cited by CNN, said.

The ride has been shut down since the accident, and will not open until it is deemed safe by a certified inspector, Jerry Hagins, a spokesperson for the Texas Department of Insurance told USA Today.  

"In addition to the annual safety inspection, amusement ride operators are required to inspect each of their rides every day and keep a log of those inspections. They don't submit (it) to us, but there's a log on premises and can be supplied to law enforcement upon request," Hagins said.

The Dallas Morning News reported that further investigations will be undertaken by Gerstlauer Amusement Rides, the German company that manufactures the rides. “We have to investigate what has happened there,” Tobias Lindnar, project manager for Gerstlauer, told the Dallas Morning News.

“I’m sure there’s no safety bar that is broken. Next week we will be on site and we will see what has happened,” he said.
