Delphine Maree Charles, 32, entered the pleas when she appeared before the ACT Magistrates Court on Monday on 13 fraud and theft charges.

Charles, of Florey, was denied bail by Magistrate Bernadette Boss as the fresh charges put the defendant in breach of her bail on 20 previous, unrelated, theft and fraud charges currently before the court.

The court heard the fresh counts related to Charles' activities on October 31 and November 1.

The alleged victims were Canberra supermarkets, department stores, a cab company, and a member of the public, the court heard.

A statement of facts was not tendered during the court appearance.

But a police statement, published on Monday morning, said Charles had been arrested after a search of home on Sunday morning alleged uncovered a number of stolen property items.

Police said they would allege the woman knocked on doors and asked for help from good Samaritans in Charnwood, Florey and Belconnen, saying she was in danger at home.

They said that in one instance, the homeowners allowed her inside their home and she subsequently stole a credit card and bank card, which she later used to purchase goods.

The police statement said two other people were also arrested from the same Florey residence earlier on Sunday morning, one for a breach of bail and the other on a first instance warrant.

Charles was remanded to reappear before the court in January.
