North Wales Police have growing concerns for 33-year-old Rowan, who has been missing from the Bangor area since Sunday evening, December 1st.
Multi-agency searches were launched earlier this week on Monday December 2nd, which subsequently led to his car being found near to South Stack lighthouse.
Searches by the coastguard and police to locate him are continuing today.
Sergeant Maggie Marshall said: “I am appealing to anyone who was in the South Stack area on Sunday evening or on Monday, and may have seen Rowan or a turquoise Vauxhaull Astra, to contact us.
“Searches to locate him are ongoing today, and officers are keeping in touch with his family.
“Anyone with information is asked to contact us by calling 101, or via our website, quoting reference 48441.”
