The suspect, who is also 14, was taken into custody at the scene and charged with gang assault early Saturday. Police do not have enough evidence to charge him as the stabber, officials said.

A 14-year-old has been arrested in the fatal stabbing of a young teen during a brawl inside a Queens McDonald’s, police said.

Shortly after the incident, a teenager was held on suspicion of wounding with intent. A second was arrested just before midday on suspicion of conspiracy to commit grievous bodily harm. Both remain in custody.
