A 20-year-old man has been charged over a stabbing spree at Lone Star College in Texas. 14 people were injured.

Harris County sheriff's office says Dylan Quick went from building-to-building using a razor-type knife to attack his victims.

The campus where the attack happened in north-west Houston has about 20,000 students.

According to a sheriff's department statement issued last night Quick told investigators who questioned him that he had harboured fantasies of stabbing people to death since he was in elementary school, and that he had planned the attack for some time.

Two in critical condition

Fragments of the blade used in the assault were found in at least one of the victims, and additional broken blade pieces were recovered from "the area where the cutting occurred," the sheriff's office said. Of the 14 people injured 2 were listed in critical condition.

This incident was the latest in a series of attacks at schools across the US during the past year.

A shooting in Newtown, Connecticut last December left 26 people including 20 children at Sandy Hook Elementary School. In California back in January a student armed with a shotgun opened fire at a high school critically wounding a fellow student before two adult staff members talked the boy into giving himself up

The attacks have prompted calls for tighter US gun control laws.

The university website says campus will reopen for regularly classes from today and that counselors will be available to talk with students and employees.
