Meanwhile, At The Police Station

The first police presence came in the form of a formation of drones, small and silver, hardly visible in the morning light. They flew from their base, along Hyacinth Street, and collectively pulled into a dive as they approached.

An unobtrusive antenna atop the van swivelled, tracking the drones, as each in turn abruptly broke formation, cut off communication, and piloted themselves into the parking garage.

Captain Khan, of the city police department, scratched her head. This had never happened before.

"Any leads on what their target might be?" she asked, turning to an entering intern.

The intern replied, stammering slightly, "Er, we think it's Kerr Bank. Small local bank, currently upgrading its security. Probably trying to alter the data in its records."

The Captain took the intern's clipboard and leafed through it. Sonic weapon... Garage-mounted speakers... Concussion without damage... Legal consequences...

She looked up, and said to the intern, "Get roadblocks up around the block. And get the team."
