A second teacher has been arrested in connection with horrifying abuse allegations at the Los Angeles school where an alleged child abuser carried out sick acts on students for decades.

Martin Springer, a 49-year-old teacher at Miramonte Elementary School in south east Los Angeles, was arrested on Friday after two seven-year-old students allegedly made accusations to the Los Angeles County Sheriff's Department.

Parents of children who were taught by the Los Angeles teacher charged with multiple counts of lewd conduct are outraged that the school let his vile acts go on for so long, RadarOnline.com has exclusively learned.

As RadarOnline.com previously reported, longtime elementary school teacher Mark Berndt was set to appear in court on Wednesday to be arraigned on 23 criminal counts of suspicion of committing lewd acts upon a child.

Now concerned parents are speaking out against the school after graphic details emerge about the gross molestation he performed on more than 23 kids, which included taping their mouths shut, letting live cockroaches crawl on their faces, and feeding the boys and girls a clear liquid substance, which subsequent tests showed to be semen.
