A Brooklyn charter-bus-company marketer stole more than $1 million in amusement-park tickets — and authorities are investigating whether she may have used some to go on a personal wild-ride bender, officials said Wednesday.

Rosemarie Bader’s scheme ended when her bosses at a charter-bus firm discovered she had allegedly used a company credit card to buy 40,000 tickets to Six Flags Great Adventure in Jackson, NJ, and Dorney Park in Pennsylvania.

Authorities allege that Bader, 51, who worked as a sales director until she was canned, ordered more tickets than necessary in order to stockpile them.

The company for which she was working, Best Trails and Travel Corp. of Red Hook, offers private and corporate charter-bus packages to locations including regional amusement parks, with the packages commonly including admission tickets.

Authorities said that while they know all of the tickets were redeemed at the parks, a law-enforcement source said they are still investigating if Bader sold them for cash — or used at least some of them herself during the scam, which ran from January 2014 to November 2016.

Bader was arraigned on various grand-larceny and possession-of-stolen-property charges Wednesday before Brooklyn Supreme Court Justice Danny Chun.

She was ordered held on $500,000 bond.

If convicted, Bader could face up to 25 years behind bars.

“This defendant allegedly engaged in a long-term and large-scale fraud scheme, stealing over $1 million in property from her employer, a local business in Brooklyn, which entrusted her with its credit card,” Acting Brooklyn District Attorney Eric Gonzalez said in a statement.

“We intend to hold the defendant fully accountable for her egregious acts.”
