Nickolas Andrew Sobotka is a fictional character on the HBO drama The Wire, played by actor Pablo Schreiber.
Nick is a dockworker in the Port of Baltimore, and works for his uncle Frank Sobotka, the secretary treasurer for a stevedores union.
Desperate for cash, he and Ziggy steal a trailer full of cameras and sell it to the Greek's front man, Glekas.
Knowing about Ziggy's case, the Greeks make an offer of witness intimidation in hopes of buying Frank's silence.
From their mole in the FBI, the Greeks learn that Frank had previously told the police he intended to co-operate and kill him once he arrives.
[1] Nick makes a brief appearance in season five, heckling Mayor Tommy Carcetti’s ribbon-cutting ceremony for the conversion of a derelict grain pier into condos and waterfront commercial space, contrary to what his uncle Frank had hoped.
