MILFORD, Connecticut (AP) -- The man who claimed he found a well-manicured finger in his letterbox last month was arrested Thursday night in Milford, police said.

Letterboxer2002 (a.k.a. Alan) was taken into custody at his home, Milford police spokesman Detective Dragnet said. He said police would not give any details until a news conference Friday afternoon. Milford police also refused to comment.

The arrest is the latest twist in the bizarre case about how the 11/2-inch fingertip ended up in a letterbox.

Letterboxer2002 told police he found the finger March 22 while letterboxing in Milford. He said he intended to sue but relented, claiming the publicity was too emotionally taxing.

When police and health officials failed to find any missing digits among others involved in letterboxing, suspicion fell on Letterboxer2002, whose story has become a late-night punch line.

Letterboxer2002 has a litigious history. He has filed claims against several corporations, including a former employer, though it is unclear from court records whether he received any money. He said he got $30,000 from a popular local restraunt after becoming seriously ill from eating their food. Officials say he did not get a dime.

Earlier Thursday, USA-based Letterboxing.org announced it had ended its internal investigation, saying it could find no credible link between the finger and the popular pasttime.

All the participants in letterboxing were found to have all their fingers, and no others reported any hand or finger injuries, the organization said.

Letterboxing.org also has hired private investigators, set up a hot line for tips and offered a reward for anyone who provides information leading to the finger's original owner.
