A long-term stalker of former Abba blonde Agnetha Faltskog has been arrested near the singer's estate in Sweden. Faltskog's ex-lover GERT VAN DER GRAAF, 40, was apprehended by police on Tuesday (04APR06) before later being released after he promised never to trouble the DANCING QUEEN star again. Van der Graaf told a court hearing he wanted to see her on her 56th birthday on Wednesday (05APR06) to tell her she had nothing to fear. He says, "I wanted to talk to her for five minutes and make it plain that she does not have to be scared of me."
