Police have warned members of the public not to approach an elderly woman from London who has gone missing in Belfast.
Patricia Dolton was reported missing to the Metropolitan Police Service in London on Monday, November 10.
However, she is believed to have travelled to Belfast on Thursday, November 6.
The pensioner was one of two missing women police in Belfast issued appeals for information about yesterday.
The 68-year-old is described as being approximately 5ft 2ins tall, of medium build, with brown curly hair.
She also has a distinctive 10 inch vertical scar on her left ankle.
Members of the public are advised not to approach Patricia directly, but to make contact with police immediately.
Detective Chief Inspector Gary Reid said: "Patricia had been living in London and we believe she arrived in Belfast on November 6, 2014.
"Investigations have revealed that Patricia was in the Donegall Place area of the city centre on November 7, 2014.
"Patricia had been receiving regular medication for mental health issues when she was living in London.
"We believe that she may not have had medication since October 23, 2014, which may mean that her behaviour could be erratic.
"For this reason we are asking members of the public not to approach Patricia directly but to contact police immediately on 999 if you know of her whereabouts."
In a second appeal, the PSNI said it was increasingly concerned for the welfare of a missing 38-year-old woman.
Kate Lauren White was last seen leaving the Mater Hospital in north Belfast at around 11pm on Sunday.
She is described as being approximately 5ft 5ins tall, of slim build, with long blonde hair.
"When last seen, Kate was believed to have been wearing a black coat and jeans," said Detective Sergeant Kenneth Leckey.
"I would ask Kate, or anyone who knows of her whereabouts, to contact Tennent Street police station on the non emergency number 101."
