London: Lindsay Lohan is said to be under 24-hour supervision after a number of scratches were found on her arm.
Officials at California`s Lynwood prison had earlier been told to look out for self-harming by medics at the nearby Lofts medical centre, reports the Mirror.
"They are suitably worried by the marks to confiscate her prison-issue toiletries,” the Mirror quoted a source as saying.
They are not taking any chances whatsoever as she`s quite vulnerable.
They are not sure if the marks are fresh or from her time spent at the centre before but they certainly look suspicious," the source added.
