A Canadian who was arrested in northern Thailand for spraying paint on an ancient wall says she's sorry for what she did and terrified about what comes next. Brittney Schneider, 22, was in Chiang Mai last Thursday when she said she and some others got "ridiculously drunk." They started to walk back to their hostel, but came across a bottle of spray paint and picked it up. "I came to as I finished writing the B and I stopped because I knew it was bad," she said Tuesday in an email interview with The Canadian Press. "But it was already too late." Security camera footage shows Schneider, who is from Grande Prairie, Alta., and Furlong Lee, 23, spraying paint on the walls of the Tha Pae Gate in the city of Chiang Mai. They have been charged with vandalizing registered ancient artifacts, which carries a penalty of up to 10 years in prison and a fine of one million baht ($40,000). Police said Lee, who is from Liverpool, England, admitted that he wrote "Scouser Lee" on the wall, while Schneider wrote the letter "B" underneath it. The 13th-century Tha Pae Gate is part of an ancient wall that forms a square around Chiang Mai's inner city. After they sprayed the wall, they walked back to the hostel and went to sleep, Schneider said. ... Good luck girl! 10 years in a Thai Jail is no joke!
