スーツケースを持ち地下鉄に乗ると後から少女たちの集団も乗ってきて私を囲んだ。 
As soon as I got on a subway carring my suitcase, a band of girls also got on board and huddled around me.
右側から1人の少女に話しかけられ相手をしていた。 
I was spoken to by one of the girls from my right side and was preoccupied with it.
気づくと、左側の少女が自分の服を私の鞄に被せその下で私の鞄に腕を入れて 
中を探っていた。 
Before I realized it, a girl from the left had been pickpocketing my bag while covering the sight with her jacket.
私は彼女の腕を掴み鞄から出した。 
I grabbed her arm out of the bag.
凶器を持っているかも知れないと考え、捕まえたりはしなかった。
Fearing they might have some deadly weapon, I didn't catch them on the spot.
