Overnight police, helicopter pursuit: Woman attacked with knife in robbery - UPDATE

KOMO reports a woman was robbed at knife point and cut on the wrist:

A woman sustained cuts to her wrist when she was robbed at knifepoint in the city's Capitol Hill neighborhood early Wednesday morning.

Police said a 20-year-old woman was robbed at 10th Avenue East and East Highland Drive just after 2 a.m.

UPDATE 8:07 AM:
CHS found this eyewitness account posted to Facebook:

... after getting halfway down the stairs, then running back inside for my cell phone, I made it outside and saw a woman bent over at the corner, holding her arm out and crying. I ran down the block and got there just as a few other guys came up. One dude had almost witnessed the attack and had ran inside to grab something to put over the gash in the woman's wrist. He ended up grabbing a grey pair of underwear. At least they came from a freshly laundered pile of clothes. I used it to hold the bloody cell phone she handed me, so I could call her friends. One after another, her friends weren't there.

She wasn't going to die from that cut, but there was blood spattered all over, a knife laying a few feet away and the cut wasn't helping her keep her composure any. Overall I think she was handling herself pretty damn well.

The police pulled up almost right after I got there. Nice dude. Calm. Not the hyped up, yelling type.

Poor girl had almost made it home when the guy following her had attacked. She held onto her purse as long as possible, because it had her green card and other necessary documents. She was from Britain and was supposed to fly back on Monday for a wedding.

UPDATE 8:17 AM:
Here's the report from the Seattle Police Department. We'll talk with them to see if we can get any more information and updates later this morning.

On 7/8/09, at approximately 2:18 a.m., an officer was driving northbound on 10 Av E., when he was flagged down by the victim. The victim was screaming and pointing at the suspect who was running east on E. Highland Dr. The officer followed the suspect and engaged in a foot pursuit. According to the victim, the suspect confronted her and demanded her property at 10 Av E. and E. Hightland Dr. The suspect pulled a knife and cut the victim’s purse straps. A struggle ensued and the victim fell to the ground at which point the suspect cut her once on the wrist. When the suspect saw the police car, he fled on foot. A K-9 unit attempted a track but did not locate the suspect. All of the victim’s property was located and returned to her. The victim sustained a minor cut to her right wrist and slight bruising to her head. She was treated on scene by Seattle Fire Personnel and transported to an area hospital as a precaution. The suspect is described as a black male, 6′ tall, short hair, wearing a white T-shirt and dark pants.

Two accounts on CHS of a police chase near 10th Ave early this morning.

First, from Dejilg Ko:

My neighbor was awaked by helicopters overhead for 1/2 hour, police cruising down our street (10th Ave E, near Brix) multiple times (no siren), and she's sure she saw a cop with a police dog walk down the street. She was scared and called the police, they would only tell her that they were chasing a robber. Anyone else have any info?

The other from aurorafix:

Hia, So I woke up at 3am this morning(July 8th) to some helicopter/large planes practically dive bombing my apartment for like 20 minutes. It got to the point where I thought they might be trying to land on Broadway or Volunteer park.... I'm on Broadway & Aloha. I looked on the news and couldn't find any escaped convicts/ crazy traffic reports or similar explanations for the wierdness.

Does anyone know what the deal was? Or did they hear it too?
