The mother of an 8-year-old called police Tuesday from the Fairfield Urgent Care Center on Stillson Road to report an older boy had slammed her daughter's head against a window while she was riding a school bus.

The child, who attends the Six-to-Six Magnet School in Bridgeport, was crying when she got off the bus, police said. The same boy allegedly did the same thing the previous day, according to the report.

Police are investigating.
