The sister of Michael Cullen has issued a heart felt plea for her brother to return home or make contact with the family.
The 33 year old hasn't been seen since leaving the family home in the North Circular Road area of North Belfast last Tuesday, January 9th.
Searches have resumed in the Cave Hill area of Belfast where friends, family and rescue workers have spent much of the weekend.
An appeal for help has also been issued in the Republic of Ireland as Mr.Cullen had a number of links in Dublin.
The Ulster University research officer was also a top 'Beat-boxer' and had supported major artists like Stormzy.

When last seen, Michael was wearing a dark green parka jacket, grey jumper and black jeans.
He's described as being 5ft 9ins tall and of thin build, with short dark brown hair and brown eyes.
Online fundraisers have also collected more than £8,000 to support the Cullen family and their search efforts.
