Tatum O'Neal has been branded a liar by the man arrested for selling her drugs in New York last month . Allen Garcia claims O'Neal hounded him for crack cocaine after he had approached her begging for money - and he accuses her of breaking a promise to help him. Speaking to the National Enquirer from New York's Riker's Island jail, Garcia says, "She said in an interview that she was going to help me, but neither she nor anyone else connected with her has contacted me since I've been in here." And Garcia insists the Paper Moon star should feel compelled to help him - because she's the reason he's behind bars. He adds, "She took a long look at me and immediately started questioning me about drugs. She was very insistent and wouldn't take no for an answer, or leave me alone." After they negotiated a price, Garcia claims he went off to buy the drugs. When he returned, cops swooped on the pair, arresting both. The 44-year-old actress pleaded guilty to misdemeanour charges and was fined and ordered to attend two half day drug-treatment classes. Garcia, 31, claims he now faces deportation to Mexico.
