An argument about wearing a mask has led police to charge a man with assaulting a security guard and stabbing a man during a horrific fight at a northwest Sydney shopping centre.

A 25-year-old man, a woman and two children were at a shopping centre on George Street, Windsor at about 8.20pm on Tuesday when a security guard asked the woman to put on a mask.

Police say the man then allegedly pushed the 59-year-old male security guard before punching him several times.

A 53-year-old male member of the public attempted to intervene. However, police say the two men were involved in a fight before the younger man produced a knife and allegedly stabbed the older man in the leg.

A customer and the security guard were able to restrain the 25-year-old man until officers from Hawkesbury Police Area Command attended the scene.

Officers also struggled with the man but managed to arrest him and take him to Windsor police station.

The man was charged with being armed with intent to commit an indictable offence, affray and resisting or hindering a police officer in the execution of duty.

He was refused bail and is due to appear in Penrith Local Court on Wednesday.
