JAKARTA, Indonesia (AFP) — Animal trappers have cut short the two-week rampage of a monkey that randomly attacked 18 people on Indonesia's Sumatra island, prompting dozens of schools to close in fear.

The animal, an adult long-tailed macaque, wounded 18 residents of the town of Tembilahan, biting and clawing at its victims — most of whom it targeted when they were alone.

Those hurt included children and elderly people.

"As of today, there were 19 attacks, with 18 victims. One victim was attacked twice," Tembilahan fire and rescue service head Junaidy Ismail told Agence France-Presse on Friday.

Some required more than a dozen stitches and a rabies shot.

The monkey was caught on Thursday in a trap set in town, and the rescue service issued a video on Friday showing it alive, seemingly stressed, in a cage.

Town official Ari Syuria urged residents to remain cautious because the monkey could have operated as part of a gang.

"The concern is that there may be other monkeys attacking people," Ari said in an Instagram post.

Forty schools remained closed on Friday, with three days of online learning ordered for hundreds of Tembilahan pupils.

Doors will reopen next Monday if it is deemed safe, the local government said in a statement.
