Police are asking for the public's help to find an elderly Portuguese woman who has not been seen for over 24 hours.

Maria Pinto - who speaks no English - left her home in Greenhithe to visit a friend in Orpington at around 8am Sunday but never arrived.

A police spokesman said the 74-year-old would have used the 492 and R11 buses to get where she was going.

Maria is described as slim, 5ft 3in, with brown hair and brown eyes.

She was wearing an off-white cardigan and had a navy blue handbag with her.

Anyone with information is urged to contact police on 01622 690690.
