The incident took place at 1.30am on the Place d'Armes, according to police reports.
The woman was thrown to the ground by her attacker, who took her handbag containing a mobile phone and her papers. The aggressor was able to escape but authorities located the empty bag some minutes later.
Police released a vague description of the attacker, said to be of average stature and wearing a beige jacket.
This incident comes less than 24 hours after a series of muggings occurred on Tuesday night in the capital city.
