Police in Japan, are looking to arrest the person behind numerous stabbings at a crowded swimming pool.
Tokyo police said that 9 women were slashed on their behinds while swimming at the Tokyo Summerland water park.
Several women were slashed at the top of each hour as swimmers were enjoying their artificial waves. After three hours, management decided to stop the waves in order to prevent more stabbings.

Two women told police that when they were enjoying the waves at 1:00 p.m., they felt pain on their behinds. They left the pool, and say blood dripping from their backsides.
Six other women reported similar attacks over the next several hours. One of the women had her swimsuit cut around 4 inches in addition to the cut on her behind.
She used a towel to cover her behind, but it quickly became stained by blood. 2 women received seven stitches each. Later on Sunday evening, a ninth victim came forward to report that she was slashed on the behind.
All women were between 18 and 24 years old. So far, no arrests have been made.
