Police are appealing for public assistance to help locate two young brothers who went missing after visiting a doctor’s clinic in St Albans last week.

Nathan and Cody Marr, aged 8 and 6, were last seen at a medical facility on Main Road East, St Albans about 9.15am on Wednesday, January 17.

It is believed that the children are travelling with their grandmother and may be frequenting the Keilor Downs, St Albans, Melton or Sydenham areas.

Police said they hold concerns for the children’s welfare due to their age and the length of time they’ve been missing.

Investigators have released a photo of the brothers in the hope that someone may recognise them.

Anyone who sees the children should contact Keilor Downs police station on 9365 3333 or Crime Stoppers on 1800 333 000.
