Police have issued an alert following reports of two suspicious men going door to door in Knights Road, Blackbird Leys, Oxford.
The men reportedly approached homes and offered to carry out gutter cleaning and gardening work.
Neither was wearing clothing carrying any company branding, and both showed interest in buying items displayed in residents’ front gardens.
Thames Valley Police community support officer Shaun Jeffrey said members of the public should remain alert and report suspicious behaviour.
Emergency incidents should be reported by dialling 999, while non-emergency concerns can be reported by calling 101 or through the police website.
The warning was intended to help residents identify potentially suspicious activity involving unsolicited visits to their homes and unsolicited approaches to buy garden goods.
