Pregnant Woman Escapes from Police in Klaipeda
LNK [TV] News reported that a woman in her sixth month of pregnancy escaped from police in Klaipeda. The woman, who has been tried 12 times before, had been apprehended for petty theft. She was taken from jail to the hospital after complaining that she did not feel well. She then escaped from the hospital after jumping out of a second floor window. The officer in charge of her did not notice that she was missing until some time later, however. The fugitive was captured four hours later.
The police are investigating the circumstances and whether the officer was properly performing her duty.
