The man, surnamed Hu, 25, is suspected of slashing several female passengers' faces on the city's subway lines 5 and 10 and was arrested yesterday according to statement by Beijing police posted on its official micro blog.
During the preliminary investigation, the suspect, hailing from the city's Chaoyang district, confessed that he resorted to the attacks due to emotional frustration, the police statement quoted by state-run China Daily said.
The man is accused of attacking five women, one of whom needed 15 stitches.
It is not known yet how long he has been attacking the women.
His attacks came as a mentally deranged person in central China's Henan Province attacked school children with a knife outside the school yesterday.
Twenty-two children were injured in the attack.
Before the arrest, the suspect's description and photos were posted on the Internet.
Cui Shaoyu, 24, an employee at a media company who takes subway Line 10 from Guomao station to Tuanjiehu station every day said she is still worried, even though the suspect has been arrested.
"When I first heard of the case through my micro blog, I thought it was fake, because sometimes online news is exaggerated.
"But I finally believed it after some portal websites published witnesses' photos with blood", she told the Daily.
Sun Yue, 24, another Beijing resident, has the same concern.
"At first I thought the man wanted to steal those women's cell phones, but after I got the truth, I was shocked. It's crazy and unbelievable," she said, adding that she will not stand near the subway's gates where the victims were injured.
