Windsor Police have issued an arrest warrant for a 36-year-old woman.
Police are looking for Amanda Cowan.
Cowan escaped police custody last Wednesday around 1pm.
Constable Andrew Drouillard says Cowan was awaiting her court appearance and while in custody she showed signs of medical distress and was taken to a local hospital.
"While at the hospital she managed to escape custody and fled the area southbound on Goyeau Street so an arrest warrant has been issued for her arrest," says Drouillard.
Cowan is facing a number of offences including theft, failure to attend court, breach of probation and escaping lawful custody.
She's described as a white, 5'9, wearing grey-blue jacket and dark jeans.
Anyone with information is asked to call Windsor Police or Crime Stoppers.
