British newspaper “The Guardian” revealed in investigations published today, Thursday, that the U.S. Immigration and Customs Enforcement (ICE) is detaining individuals for longer periods in detention rooms that lack sufficient oversight, noting that some facilities have witnessed a massive increase of up to 600% in the duration of detention.

The newspaper reported that these centers affiliated with ICE, scattered in its offices, federal buildings, and other locations throughout the United States, are generally used to detain individuals after their arrest and before their transfer or release.

Most often, these centers consist of small concrete rooms without beds, designed for short-term use not exceeding just a few hours.

“The Guardian” clarified that ICE detention centers across the country suffer from weak official oversight, raising concerns among human rights activists about the miserable conditions inside.

In the same context, the newspaper analyzed login data to detention centers, published for the first time by the Transactional Records Access Clearinghouse (TRAC), covering the period from September 2023 until late July 2025, the last month for which data is available.

The results showed that ICE used at least 170 detention centers in various parts of the country, including 25 of its field offices.

According to “The Guardian,” the policies of President Donald Trump’s administration, and its fierce campaign for mass deportation, led to a noticeable increase in the duration of individuals’ detention inside these centers. After Trump came to power, the average duration of detention increased in 127 facilities, according to the data.

Although ICE amended its regulations last June, it still violates its own policy that prohibits detaining individuals in these facilities for consecutive days.

In some cases, such as the detention center in New York City, located on the tenth floor of a federal building in Midtown Manhattan, the duration of detention increased by nearly 600% on average after the regulations were amended in June.

In one case, the newspaper documented the detention of a 62-year-old man for two and a half months inside the same center, while agency data revealed the detention of 63 other individuals for more than a week at the same site, between Trump taking office and the end of last July.

Previous ICE policies prohibited the detention of individuals for more than 12 hours in these centers, but a new memorandum issued in June 2025 abolished this rule and allowed individuals to be detained for up to three days.
