collarの名詞形

以前ブログで，Minesota君がcollarとcatchの比較をしてくれていましたが，昨日，逮捕された高橋克也容疑者に関する記事に，６月３日に逮捕された菊池容疑者逮捕の事が書かれていました。この場合もMinesota君の説明通り，catchではなく，collarが名詞で使用されていました。復習も兼ねて再度取り上げさせていただきました。（GP）

When one of the investigators asked him if he was Takahashi, he replied "Yes," the police said. He was wearing a light gray polo shirt and blue jeans.
Takahashi told investigators he had several million yen on him. He had a black business bag and a brown bag when he was apprehended, the police said. He had entered the cafe shortly after 6 a.m.
Takahashi's arrest followed the June 3 collar of Kikuchi, who is also suspected of involvement in the subway attack. The break led to the police learning that Takahashi was working for a construction firm in Kawasaki and that he withdrew about \2.38 million from a bank before fleeing.
