A woman who claims she suffered a gash in her arm that required 12 stitches after she was caught up in the Chris Brown/Drake fight madness has hired a lawyer and plans to sue ... TMZ has learned. 

Javier Solano, a lawyer representing a woman named Lucy Pavlovsky tells TMZ his client was in the VIP section at W.i.P. Nightclub when the fight went down. He says Lucy ducked down when the bottles started flying and didn't notice her arm was cut -- "gushing blood," in her words -- until she was making her way out of the club. 

Solano says Lucy took a cab to the nearest hospital, and got a total of 12 stitches to close up two cuts on her arm -- and also got a tetanus shot.

According to Solano, Lucy was interviewed by NYPD officers on Friday ...who said they were gathering evidence for a possible criminal complaint. 

Solano says Lucy's lawsuit would be against the club -- but hinted Drake and/or Brown could be included, saying ... "At this moment we are exploring all options on who will become a defendant.

He added, "I can assure you that regardless of fame, money or stature, the people responsible will be held accountable."
