The sister of a man who has been reported as missing on the north coast last night said she is praying he is found soon after clothes were found near a river.
John Thompson (56), who has links to the Ballyclare area, was last seen in Portstewart on Saturday and yesterday police put out an appeal for information about his whereabouts.
It emerged last night a sea search was taking place after clothing was found near the entrance of the River Bann between Portstewart and Castlerock.
Last night, as dozens of people took to Facebook to express their hopes that Mr Thompson is found safe and well, the missing man's sister, Sharon Rao, said on social media: "Thank you all so very much for sharing your thoughtful concerns and caring for my brother John. I pray he is found soon. Much appreciated from all the family."
A police spokesman said: "John was last seen around midday on Saturday, August 20 in the Portstewart area.
"He is described as 5ft 10ins tall, with dark brown hair and when last seen he was wearing blue 3/4 length shorts and a red raincoat. It is believed that John may have had a bicycle with him at the time he went missing."
Yesterday civilian boats, RNLI jet skis, HM Coastguard, PSNI and Community Rescue Service were involved in a search.
A Coastguard spokesman told the Belfast Telegraph last night a search from Portstewart to Magilligan got under way around 10.45am yesterday and was stood down last night to resume this morning.
