Police want to speak to him about a burglary in White Rock, Hastings, in which a burglar entered a family's apartment and stole a Kindle, an iPad and a purse.
At about 4pm on Sunday 1 March the 17-year-old daughter of the owners left her home briefly. When she returned just a few minutes later the front door was slightly open.
She went into her home and saw a man in the corridor who quickly moved past her and out of the door to escape.
Sussex Police launched Operation Magpie to tackle burglary across the county.
