伦敦警方星期四说，他们没有找到袭击者受到激进主义影响的证据，这位杀死1名女性并导致5人受伤的索马里男子应与恐怖主义无关，袭击可能是精神疾病引起的。
警方在伦敦大学附近的罗素广场用电击枪控制了一名19岁男子，随后将他逮捕。这个尚未公布身份的男子目前被警方拘留在附近医院里。
警察确认，被刺杀的女性60岁，是美国公民，她在案发现场经医护人员抢救后不久就宣告死亡。3名受伤者星期四早上已出院，另外两名伤者的情况还不清楚。
伦敦警察厅负责特别行动的助理总监马克·劳利说，警方认为，在这个案子中，嫌疑人的精神状况是一个“重要因素”，但同时提醒人们，这只是几条调查线索之一。
当地时间晚上10:30左右警方收到一通电话，报告正在发生的袭击事件。过了大约10分钟，警察赶到现场将袭击者制伏。
劳利说，作为预防性措施，伦敦街头星期四早上将增派武装警察，以便让伦敦人感到“放心和安全”。持刀杀人事件发生的同一天，伦敦官员宣布，为预防恐怖袭击，伦敦市将增派武装警察巡逻。
London police said Thursday that they found no evidence of radicalization to suggest terrorism after a Somali man stabbed a woman to death and wounded five other people in central London. Instead, they say the attack was likely triggered by mental health issues.
Police arrested the 19-year-old man in Russell Square, near the University of London, after incapacitating him with a Taser. The man – who has yet to be publicly named – is in police custody at a nearby hospital.
Police identified the 60-year-old woman who was stabbed to death as an American citizen. She was treated at the scene by paramedics, but pronounced dead shortly after. Three victims were released from the hospital early Thursday morning. The condition of two others was unknown.
Mark Rowley, the Metropolitan Police Service's Assistant Commissioner for Specialist Operations, said police believe the mental health of the suspect to be a “significant factor” in the case, but cautioned that it is just one of several lines of inquiry.
Police received a call about the attack in progress around 10:30 p.m. local time, and within about 10 minutes had arrived on the scene and subdued the attacker.
Rowley said that, as a precautionary measure, there would be an increased presence of armed police on the streets of London Thursday morning to provide Londoners “reassurance and safety.” The knife attack came the same day London officials announced an increase in armed police patrolling the city in an effort to prevent terror attacks.
