It was easy for police to nab the suspect in an apparent gas station robbery: The manager had locked him inside. A man entered the Pride store at about 2 a.m. Wednesday and demanded money, Springfield police said. The alleged robber kept his hand in his pocket, leading the manager to believe he was armed. The manager told him to leave. The thief responded by throwing a 2-liter bottle of soda, which struck the worker in the head, police said. After a scuffle, the manager locked the door as the suspect allegedly stuffed cigarettes in his pockets. Witnesses called 911 and police arrived to find the suspect locked in. Police arrested Curtis Garrett, 60.
