Someone deliberately severed about 1,400 fiber optic lines in Lincoln Heights on Monday, Sept. 7, knocking out Spectrum internet and cable service for customers in Boyle Heights and parts of East Los Angeles.

Photos released by Spectrum showed the cut lines draped across railroad tracks. Crews were splicing the fibers back together to restore service, the company said in a statement reported by The Eastsider LA.

Spectrum is offering up to $25,000 for information leading to an arrest.

The company said the fiber lines do not contain copper, meaning the attack is separate from the wave of copper thefts that has hit Los Angeles. Spectrum linked the cutting to a broader national pattern of attacks on telecommunications infrastructure.

The NCTA, the Internet & Television Association, found in a June report that 18,327 attacks struck communications networks in 2025. That was a 59% increase over 2024 and disrupted service for 11.8 million customers nationwide. Los Angeles alone logged more than 1,100 attacks last year, according to the report. California and Texas together accounted for more than half of all incidents.

The estimated cost of those outages ranged from $294 million to $1.47 billion nationally, with California accounting for roughly $252.6 million, the NCTA found.

The Lincoln Heights attack is the second time in about a month that Spectrum has reported a large-scale fiber cut in Los Angeles. On Aug. 7, someone slashed cables in Baldwin Hills, causing outages across Beverly Hills, West Hollywood and Koreatown. That attack also involved roughly 1,400 severed fibers.

"We are splicing more than 1,400 fibers that were cut to restore service," a Spectrum spokesperson said on Aug. 11 regarding the Baldwin Hills incident. The company offered the same $25,000 reward and filed a police report with the Los Angeles Police Department, according to the New York Post.

No LAPD statement confirming an investigation into the Sept. 7 Lincoln Heights incident has been made public. Spectrum's statement did not name a suspect or a motive.

Anyone with information can call Spectrum's tip line at 833-404-TIPS (8477) or contact local law enforcement.
