Indianapolis police called a special weapons team to an east-side house in the 2000 block of Euclid Avenue early Wednesday morning after a man with a gun refused to leave the home. The four-hour standoff ended about 8:30 a.m. after tear-gas canisters were fired into the home. Alex Pikes, 18, was arrested after surrendering to authorities. A woman who was also in the home through most of the incident is being questioned. Police said they don't believe she was being held against her will.
