MIAMI (CBSMiami) – Xanax and Ambien mixed with water. That’s what Miami Beach Police said they found in a woman’s purse after she was arrested for drugging and stealing from men she picked up at Miami Beach nightclubs.

What started as a night on the town at a Miami Beach club Sunday night, ended with a $30,000 dollar Rolex stolen, and Colombian national Liliana Vanegas in front of a judge.

Vanegas’ alleged victim, Canadian tourist Arvin Malhi, told CBS4’s Natalia Zea that Vanegas picked him up at a club at Nikki Beach early Monday Morning.

“I asked her, ‘Why are you talking to me, when you didn’t talk to anyone else all night?’ She goes, ‘She likes men, she doesn’t like boys,’” said Malhi.

Then he said, “She asked me if we can go to my room.”

Once in Malhi’s room at the Loews Hotel, he said Vanegas got drunk and laid down to sleep. At 7 a.m. he said he awoke and realized he was being ripped off.

“She picked up my watch from my side table, and she left. And I quickly jumped out of my bed and by then she had closed her door,” he said.

He said he caught up to her outside the hotel and confronted her.

“I said, ‘Hey, give me my watch back.’ She said, ‘What watch?’”

He called 911 and followed her as she walked away. He said he watched her get a ride from a man who police identified as, Francisco Trujillo. Investigators said Trujillo is listed as “Daddy” in Vanegas’ cell phone.

Trujillo’s defense attorney, Ray Sarmiento, said he was not part of a crime. The bond court judge felt differently and found probable cause for a grand theft charge.

Police have charged Vanegas with another similar robbery in the City of Miami from February. In that case they said she met her victim at Mango’s in Miami Beach, and went back to his condo on North Bayshore Drive, where she drugged him. When that victim woke up the next day, police said all of his jewelry was gone.

That Miami victim said the Versace necklace Vanegas wore in her mugshot belongs to him.

And when cops stopped Trujillo’s car, after Malhi’s incident Monday, and searched Vanegas’ purse, they said they found cocaine and a bottle with white liquid inside, which they say was Xanax and Ambien mixed with water.

Malhi said his lack of desire for alcohol ended up protecting him.

“Probably she had the intention to drug me as well, but it didn’t go in her favor. I didn’t drink at all and she ended up getting drunk,” he said.

After his nightmare visit to South Beach, Malhi said he just wants his watch back. The stolen Rolex still has not been recovered.
