[Ger-Poland-Volhynia] Russian Prisoner Camp near Lodz

[Renee Hundt]

In Dec 1947, my husbands grandmother (German) was falsely accused of a crime by a Polish farmer (revenge) and she was sent to a Russian Prison Camp near Lodz.  She was there for 10 months when her eldest son convinced the Russian's to release her before being shipped via cattle cars to East Germany.  Anyone have any information, possible name of such a prison?
