Tina Lunn, 37, was smoking among “No Smoking” signs at the Quincy Center Red Line station at 11:25 a.m. Sunday when she was approached by a police officer who reminded her of the no-smoking laws on MBTA property, Transit Police said in a statement.

A Braintree woman who allegedly gave police a fake name actually provided the name of a woman who had a warrant out for her arrest, MBTA Transit Police said.

Lunn provided a false name and date of birth — but the name she gave was that of a real person who was already wanted by police.

Lunn went through the arrest and booking process using the assumed name until police discovered her real identity — and that she herself was wanted by authorities in Hingham and Salem, Transit Police said.


Lunn was charged with giving police a false name during the booking process. Lunn was also issued a smoking citation.

Lunn already faced three charges of assault and battery with a dangerous weapon and one count each of kidnapping and possession of chemical Mace without a firearms identification card in Hingham District Court and a charge of larceny over $250 in Salem District Court, Transit Police said.

She is expected to appear in Roxbury Municipal Court today.
