A man has been charged following a dramatic siege in Parramatta that left a police officer injured and a woman trapped inside a home.

Sebastian Castroman Marquez, 46, faces multiple charges after he allegedly armed himself with a samurai sword and sparked a large police operation at a property on Crimea St shortly before 1pm on Saturday.

Police were called to the scene just after 1pm following concerns for welfare.

They attempted to speak with Castroman Marquez, but he refused to cooperate.

A major operation was launched, with local police joined by the Tactical Operations Unit (TOU) and police negotiators.

A short time later, a 51-year-old woman who was inside the home was safely escorted from the property without incident.

The siege ended about 2.40pm when Castroman Marquez was arrested and taken to Westmead Hospital for assessment.

During the arrest, a TOU officer sustained a cut to his leg and was taken to Westmead Hospital, where he remains in a stable condition.

Castroman Marquez was discharged from hospital on Sunday and taken to Parramatta Police Station, where he was charged with multiple offences, including causing grievous bodily harm with intent to murder, detaining a person for advantage (domestic violence-related), assaulting a police officer, and attempting to stalk or intimidate.

He was refused police bail and appeared at Parramatta Local Court on Monday, but did not make an application for bail.

He appeared with bruising to the right side of his face across his cheek and above his eyebrow, and did not say a word during his brief appearance.

He was remanded in custody and is next expected to face court in Parramatta on April 10.
