孟加拉国一位高级反恐官员星期三说，被指控在纽约地铁隧道引爆一枚管状炸弹的男子看来没有与激进组织有任何关联的前科。
孟加拉国官员伊斯拉姆说，调查人员在调查过程中与阿卡耶德·乌拉(Akayed Ullah)的妻子以及他妻子的父母做了谈话。
27岁的乌拉星期三将第一次在法庭出庭。美国联邦检察官星期二宣布对乌拉提出涉嫌恐怖犯罪的指控，罪名包括对公共场所进行炸弹攻击以及使用大规模杀伤性武器。每项犯罪都可判终身监禁。
星期二的刑事起诉书还指控乌拉对伊斯兰国组织提供实质支持、用炸弹毁坏财产、以及使用破坏性装置扩大暴力。每项犯罪可判30年徒刑。
纽约南区代理联邦检察官金俊贤(Joon Kim)在纽约的一次新闻发布会上宣布了这些指控。
乌拉的炸弹攻击发生在港务局巴士总站和时报广场两个地铁站之间的隧道。监控录像显示攻击者交通高峰期间走在人群中，炸弹爆炸后出现烟雾，人们逃离现场，攻击者躺在地上。
A top counterterrorism official in Bangladesh said Wednesday the man accused of detonating a pipe bomb in a New York City subway tunnel does not appear to have any known links to militant groups.
Monirul Islam said investigators have interviewed the Akayed Ullah’s wife and her parents as part of their probe.
The 27-year-old Ullah is due to make his first court appearance Wednesday, a day after U.S. federal prosecutors announced terrorism charges against him. The charges against him include bombing a public place and using a weapon of mass destruction, each of which carries a maximum sentence of life in prison.
Ullah was also accused of providing material support to Islamic State, destruction of property by means of an explosive and using a destructive device in furtherance of a crime of violence, according to a criminal complaint disclosed on Tuesday. These charges carry sentences of five to 30 years each.
Joon Kim, acting U.S. Attorney for the Southern District of New York, announced the charges at a press conference in New York.
The attack took place in a tunnel that connects the Port Authority Bus Terminal and the Times Square subway stations. Surveillance footage shows the attacker walking among the rush-hour crowd, and then smoke filling the area as the device goes off. The man is then seen laying on the ground as people rush away from the scene.
