A man wanted over a stabbing allegedly committed after he was recommended for deportation has been arrested.
Humberside Police said Iraqi Kurd Caliph Ali Asmar, 25, was detained in central Hull on Wednesday evening.
He is to be questioned over an attack on a man in Beverley Road, Hull, on Good Friday, as well as the sexual assault of a 15-year-old girl in March.
Mr Asmar, also known as Shwana Ali Mohammed, arrived in the UK in 2001, but was refused asylum.
Four other men, aged 32, 29, 25 and 19, were also arrested on suspicion of assisting offenders.
A Humberside Police spokeswoman said five men were now in custody at Queens Gardens and Priory Road Police Stations.
The arrest comes as the Home Office said the hunt was continuing for hundreds of foreign criminals who were released from prison between 1999 and last month without being considered for deportation.
Home Secretary Charles Clarke told MPs on Wednesday that about half of the 79 most dangerous offenders remained at large.
He announced plans to toughen the law to introduce the principle that foreign nationals who commit a crime should "expect to be deported" at the end of their prison sentence.
Deportation proceedings have begun against 574 of the 1,023 released men, he said.
